....due to some medical issues, but...

...now I have to finish sand and buff out the job that was done 2 years ago.

The paint is a 2 stage dark metallic grey (2013 Dodge Granite Crystal) with a light pearl content base coat and lots of clear. There are some runs and orange peel, so at least I know there's enough clear to cut some off. It has flattened down and hardened quite a bit.

Already have used 600 to 1500 to block down a large run to a tolerable wave. So my skills are still intact, but I need to know what the latest and greatest liquid materials are available to finish polish, etc.

My favorite parts place has gone OOB and nothing I see in Autozone or the like have anything I want to use, as they don't list the size of grit in the polish (Meguires, etc). My last job, there was a bottle of 5000 and 10,000 grit liquid to use with the buffer. Definitely need to know what the numbers are before using them.

Any info would be appreciated.

thx

I really like the 3M "Perfect-it" series compounds.
You can find them on line at auto stores and even "E-Bay"
They have 3 that are numbered 1, 2 & 3.
No. 1 is a really fast cutting compound, and feels like it has no grit but
sure cuts like it does. I love this stuff.
No. 2 is a medium compound for bringing up the finish to nice shine, and
No.3 is a swirl remover that I usually don't use unless it's a dark color.
They come in purple bottles and it's not cheap.
A qt. of No.1 runs around $40.00. (but it's worth it.)
I usually start out with a wool pad and finish up with foam.

Also Meguiars has some pretty good stuff too.
And they're labeled pretty simple to understand,
like "heavy cut" fine cut" etc.
I hope this helps, good luck 8)

I just read on another forum that Megs is basically the 3M Perfect It with some fillers added.
Does anyone know if this is accurate?

I'd heard that as well. Really wouldn't surprise me as there are fewer and fewer raw sources for a lot of the abrasives and chemicals now. Even if it is true proprietary fillers could make quite a difference in the speed/performance of the product. One of my old professors use to say, "Anybody can get a frying pan and hamburger, but that does not make you McDonalds."

I use both and they don't seem the same to me.
The 3M No.1 cuts way faster than the Meguiars "heavy cut"
And they look and feel totally different.
3M doesn't have the gritty feel that Meguiars has.
But Meguiars has so many different ones it's hard to say which
one may be the same.

Why would a compound have fillers? I can understand fillers in a swirl remover or polish but in a compound?

Most have an abrasive that wears down with use and that's what appears to be a filler - simply because it fills everything it can get into.

That said, I use the 3M for heavy cutting or ceramic clears because the abrasive, whilst not so gritty as some others, seems to be very hard and lasts a bit longer. Leaves a horrible residue though that is difficult to get off. Some of the newer compounds seem to have overcome this problem.

The "fillers" is glaze, most all compounds have glaze.
They "fill" the scratches so you don't see them.
That's why it may look good until you wash it, than scratches reappear.
I've heard that "Presta" brand compounds are what a lot of pro's
prefer just because it has no glaze in it.
That is a good thing when buffing/polishing up through the grits.
But washing in between is always best for seeing what you really have.

I have used Megs years ago and Liked it. I Bought into the whole 3M Perfect it system all of it hook line and sinker and Hated it. I even have the compleet Perfect it system Training video on Disk I found it to be Over complicated with way too many steps and very time consuming and its very over priced 3M super expensive as well all of it!

Switched to Presta Products and haven't looked back since! Very Very happy with it.
I change and wash My pads frequently while Buffing I hate hallo's!

because thats what compound, and waxes are for is filling scratches, yes that is why after you wash a car a few times the scratches seem to come back, truth is they was never gone.

most painter "think" they polish properly but reality is they do not
