aaaaaaaand the saga continues...

im SO close.
so im having a hellava time getting this turbine to lay down paint flat. always has a bunch of orange peel.

so my latest bright idea was to load a test panel with paint so that when I wet sand I wont burn through. I put 5 wet coats on.

wet sanded and buffed... and guess what? no deeper looking scratches like I had been getting. Problem solved... but not so fast...

NOW there was still orange peel visible after buffing.. so I guess spraying coat after coat of orange peel is a no no? do the coats not melt into eachother? the orange peel LOOKS flat but you can still see it in the reflection. I will get pics tomorrow.. I will also try sanding a little deeper tomorrow and see what happens.

it basically looks like factory orange peel finish now,,looks pretty much like my 2018 fusion paint LOL . not exactly what I was going for.. but acceptable I guess..

You are not getting it sanded flat (no orange peel) during your initial sanding step.

This is what orange peel looks like when sanding:

Panel should look similar to this:

Here's a panel sanded 1000, 1500 and 2000:

Did you try the twisted wool pad and a rotary buffer? It won't take out orange peel but once you get them sanded correctly it should really make your panels have clear reflection and nice shine. The next stages of buffing are to increase that clarity and remove any swirl marks.

the twisted wool is in the mail. waiting for it to show up. im excited to give it a try.

heres the mess I got myself into now haha.

after spraying: OBVIOUSLY a boat load of orange peel... I just figured if I put a bunch of paint on I can sand the massive amounts of orange peel without burning through.

the boarder of where I stopped sanding showing the difference:

this is sanded with 1500..i continued to sand with 2000 after this point:

and this is how it came out... quite wavy and orange peely… you can see mostly in the left side of the garage door reflection.

I only tested on the top of the panel... so today im going to try sanding deeper. it looked like the orange peel was gone but I guess not. I have been talking with experienced turbine people on how they get the paint to go down flatter so i will experiment with that aswell.

i am using a foam sanding block "soft sander" cut to fit the sandpaper pieces perfectly ...should i use a hard block?

just spent way longer than any person should just working on that one spot (before putting the work in on the entire panel) went from 1000 to 3000 have NOT buffed yet.
this is what i got... not a lick of orange peel on this mug (upper portion}.

yet you can still see a ton of waves (orange peel-esque?) most noticeable in the roof line and bricks under the window.
im missing something xD

Any place you still see a shiny spot in your sanding process is a place the sandpaper hasn't hit.
If you think of the surface as that of an orange (hence orange peel) it has lots of bumps on it. The idea is to sand those bumps level to the surrounding surface. You will not do that with too soft of a sanding block because it flexes.

Durablock makes a decent firm block for this: https://www.amazon.com/Dura-Block-AF440 ... B007VTSVDQ

As stated previously I use a piece of oak for this purpose. It is flat and non flexible.

Once you have the orange peel removed and the surface flat, Motor Guard makes a nice flexible soft block for use the finer grits 1500 and up. https://www.amazon.com/Motor-Guard-SB-1 ... B003WUYG1E
