Should I sand between Epoxy coats? I know epoxy is kinda hard to sand. I do have a couple of areas that will need filler, but I wasnt sure about sanding between coats.

Depends on how long between coats?

Epoxy I use You can wait up to a week between coats without sanding.

You should have removed door handles locks and the mirrors, door window trim.
details make or break a great job.

Hard to tell in that Pic but do you have any texture at all in that coat? hard to see in that pic.
Wont zoom in enough, You should not have any orange peel, epoxy should lay down nice and smooth.

The mirrors were cracked at the base and glued from someones past repair. Once I got into the doors, the mess was enough to back out and pretend I didnt see it. :shock:
There is some orange peel . Thats why Im asking if one should sand between coats. I sprayed the Epoxy at 3pm yesterday (Pacific time)

You should read your Paints Tech sheets for re-coat window. Your Tech sheet will also tell you How much it can be reduced, What the suggested Spray technique is and what pressure to spray it at and what size fluid tip to use in many cases.

You also need to figure out why your getting Orange peel now and cure that problem first! As I said b4 Epoxy should go down nice and smooth similar to Base coat.

Your fluid tip and air pressure spray pattern & gun distance from panel all need to be spot on.


Get a close up pic of your work please and post it, how bad is it?
What Air pressure did you spray at?
What distance was your gun to the work?
Did you reduce your epoxy? if so how much?
Where is you air regulator at? Is it on the compressor? is that the only one in your system or do you have another in the system?
Are you using one of those Desiccant air driers ? If so is it the type that goes on at the base of the gun?
Where are you reading your Guns spray pressure at? at the regulator at the compressor or at the Base of your gun? Please Explain in detail how your adjusting your guns air pressure?
Are you using Hi flow Air fittings or regular quick disconnect air fittings?
Please explain in detail how you are adjusting your gun b4 you start to paint????

These are lessons that need to be learned now before spraying more!
Correcting the Orange peel now is critical, so Stop and let the epoxy cure out and sand it all back down flat now before proceeding.
Allowing the epoxy to cure could take a week or more to fully cure depending on your local temps, so you have time.
Learning how to stop Orange peel is a lesson you have to learn ASAP! Before any more Painting!

You mirrors could have been repaired now or replaced, better now than latter.
What stopped you from pulling door handles? Your car is in Paint shop Jail now dont be expecting this project to be done in a week or two Your using Epoxy, Epoxy requires a long time to fully cure, Regardless of what some may say Epoxy shrinks you need to give it time to shrink!
Doing a complete Paint job is NO easy, cheap or fast task to do correctly, it is a lot of work! it takes TIME! so get out of your rush!

There are reasons body shops want so much to paint a car "DETAILS" Things few ever think about or see BUT Many are always quick to Judge and point out all the flaws regardless if they have ever tried to do the work themselves or not.

Their are reasons Body shops don't use Epoxy, It takes time for it to cure, its too slow for body shops. Even your 2k Primmer needs cure time best done in the sun, Allowing Primmer coat to sit out in the sun for few days to a week is not unheard of especially before Base and clear. As I said Paint shop Jail.

In the end its up to you, Do You want to have a Ten footer that looks like a dog Turd up close or you can put the time and effort into doing a nice Job that you can be Proud of.

If you ask me You had a Ten footer to start with and you weren't happy with it.
In the end its your Time and money your spending!

It doesn't cost more to do it right It takes a little more time! a little more work and a little more effort And When your learning at the same time Your gonna make mistakes that require REWORK! its frustrating as hell but Better to learn from those mistakes now head on and do the rework now Because You'll make more different mistakes on your 2nd, third or forth Paint project you do! ask me how I know?

Painting cars is an incurable disease Once you've been bitten their is only one cure! to treat the symptoms...

SANDING! :rotfl:

Thanks or the advice (and the rant too :? ) You might think I'm some spoiled kid who wants everything handed to him. To be transparent; I'm a retired senior with a terminal disease. This is a "bucket list" project. I dont have any dreams of opening a body shop, or entering this car into a custom "resto mod" show; My wish is to be driving autocross events and getting groceries! :bored:

Winters here where I live are harsh. So we do work in a rush. The car will be stored in my garage during the winter. And if Im blessed enough to be around still next March; Ill have a pretty fun little car to scoot around in. (Even if it is a polished dog turd)

Please don't take my words as harsh, please! the Internet is devoid of emotions Not trying to talk down to you but to encourage you to do your best.

:bighug: :allgood: :cry: :whoops:

Many of us here are Older I am no spring chicken myself and believe me Not in great health either! Lets stay on positive side of things Ok?
:whoops:

Their is sooo much to know about Painting cars! So much to know about all the equipment necessary to pull off a decent paint job as well its impossible to just sit down and say A B C D E F unless you write a Book no one is going to read and even then things get left out.

:flatten:

I could tell by the pics of your shop You have some talent, knowledge, tools and equipment and good taste as well as you had an Old Mopar you had to sell off, Your a Mopar guy so you cant be all that bad lol

:goodjob:

As I stated B4 Please answer the questions I wanna help I am not there and cant see what you have and what might be wrong, You kind of hit on one of your problems in other post saying you had an air problem. Constant reliable clean dry air is a Must!

again please elaborate on questions Take pics they are worth a thousand words. :goodjob:

What Air pressure did you spray at? 28lbs. 2.5 tip; sheet says 1.8 - 2.2 if I'm remembering right
What distance was your gun to the work? 4-8 inches
Did you reduce your epoxy? if so how much? Just the standard 1:1 ratio
Where is you air regulator at? Is it on the compressor? is that the only one in your system or do you have another in the system? One on the tank; 1 a couple of feet from the tank; and one pre gun. * The gun one came in a kit, but it was leaking from the housing
Are you using one of those Desiccant air driers ? If so is it the type that goes on at the base of the gun?Attatches to the handle, then hose
Where are you reading your Guns spray pressure at? at the regulator at the compressor or at the Base of your gun? Please Explain in detail how your adjusting your guns air pressure? 120 lbs in tank; 5 HP 80 Gallon
Are you using Hi flow Air fittings or regular quick disconnect air fittings?Quick disconnect
Please explain in detail how you are adjusting your gun b4 you start to paint???? Turn the hose pressure to 40 lbs. then adjust gauge to 28 or so lbs.at gun NOTE: fittings leak a bit. Thats why I turn the first gauge to 40

You mirrors could have been repaired now or replaced, better now than latter. The mirror problem is horrible. I'm hiding from it. I dont understand automotive electrical
What stopped you from pulling door handles? Escaped the mirror problem. The original (to me) paint has the handles the body color. I masked the lock exterior and called it goodYour car is in Paint shop Jail now dont be expecting this project to be done in a week or two Your using Epoxy, Epoxy requires a long time to fully cure, Regardless of what some may say Epoxy shrinks you need to give it time to shrink!

What Brand Epoxy?
28 lbs mmm sounds ok BUT I shoot it a little higher pressure myself.
2.5 Fluid tip???? Yikes! I would only use that for Feather fill or other Polly cement crap!
That 2.5 will pour the Paint on especially at 28lbs Yikes, 1.8 fluid tip would be a Minimum and I always spray epoxy with a 1.4 myself even un-reduced.

Spray distance 4-8 inches? also No!
Stretch your pinky and thumb out just as far as you can place tip of pinky on wall and tip of thumb on tip of Business end of gun That's your distance stays ruffly 6 inches always and you must maintain it like a robot!!!!!! Like a ROBOT! ALWAYS!

Regulators Air filters and Quick disconnects :
This is a Big one ok I take it your shop is not plumbed for air in Pipe?
I also take it you haven't built a water Trap yet?

I will try to explain mine as an example.
My shop is plumbed full pressure strait out of tank to the full shop No regulator, Air comes out of my tank goes through 80 ft of pipe too cool the air before two large tanks that act as a water trap very effective at trapping water! then through a single large air filter then it is plumbed around the shop in 1 inch pipe with Regular old cheap Quick disconnects where ever I needed till it gets to my Paint booth where I have a water filter, then a oil filter and a Desiccant drier then onto my one and only air pressure regulator all on my Paint booth wall.
Do you need all that NOPE!!! absolutely not!!
I do however suggest a Water trap of some sort and a Good air filter and a Good descant drier if you can afford it?

Its at this point I only have Hi-flow air fittings for my dedicated air hose for painting.
Its here where I set and control gun air pressure
The importance in spending an extra $30-$40 on Hi flow fittings cant be stressed enough You need em! regular fittings are too restrictive not enough air flow!
Loose your desiccant drier Ball at base of gun they are also restrictive and restrict air flow unless its a Devilbiss descant snake drier they work pretty good. Their about $40 from Devilbiss.

If you have one of those air valve deals with air gauge at bottom of gun always leave the Air adjustment wide open ALWAYS! NEVER close it or restrict gun.
Always adjust air pressure at the main air regulator with paint gun trigger pulled fully and adjust pressure to what you want with TRIGGER PULLED! air flowing through the gun.

Now take gun open fan control all the way Leave it like that never close it!
Now Take fluid control knob Pull gun trigger fully screw fluid control knob in till it just starts pushing on the trigger This is full open turn it in EXACTLY one half turn more in.
Now paint gun is adjusted to do its job atomize Paint.

Now gun can be used as is I painted exactly like this for years BUT The gun drives YOU! OR you can learn to adjust it ????? Let me know if want to learn how a little more complicated but there are a couple of good videos on you tube that explain it pretty good.

If you got air leaks FIX EM! You cannot cheat and just add more pressure to over come it.
Doesn't work that way, Its Not air pressure we are worried about any way its AIR FLOW Unrestricted air flow Paint guns need a lot of Air to work correctly not pressure.

Think of your Paint gun as a Carburetor Its only job is to atomize fuel and it does that with 14.7 psi atmospheric in most cases BUT CFM can range any where from a couple hundred CFM to 1300 + cfm same PSI used in all. understand? YES? NO? ?????????

Again Hi flo fittings!!!! They are Needed! I cant stress that enough!


You dont need a Big elaborate expensive air system if your smart but yours does need some tweaks to get it ready for Painting duty's once its done you don't need to redo it though.



Getting this done by Oct should be a Problem
And its your wifes Garage ?
Man we gotta Talk lol
My wife don't go near my Man caves That be Heman woman hater club Territory!

I'll respond tomorrow. Haha! You are a crackup! Do you have a YouTube channel? Because I think I've watched you! "He man woman haters" ! Thats a riot! Ive got a Our Gang/ Little Rascals DVD somewhere around my daughter gave me a few years ago! Im gonna have to find it!
So I've been block sanding the car all day and I don't have half done yet. I had forgotten way back when I had my 65 Dodge Dart that I splurged on a new paint gun. A Devilbiss Finish Line with a 1.4 tip. I found it in the back of my paint cabinet. Its never even been opened up! Now Im gonna have to learn how to use it.....CORRECTLY! Like you said; I don't want to have a polished dog turd! Darn Im sick of sanding! I feel like Moses's sandals! I'll respond to your text tomorrow. Have a good evening, I got a Dodger game to watch. Thanks bud!
