Dry color sanding?

Discuss anything after that final masking comes off.

I'll have to look into that, my DA can run at a snails pace if you want. And yes I do believe it's a much lower solids even though they call it the good stuff. There's very few options where I am, basically one place that has everything autobody related. I sure do hate those pig tails.

Letting that clear harden up more helps a lot too.
Just another reason I don't like some of these new clears that
boast they can be easily rubbed out a week later, they stay soft.
Give me a clear that gets rock hard in a couple days and it
makes sanding easier to me, as long as I get to it the next day like I
always do.

Well at the speed I move it has plenty of time to harden up, too much if anything. Although it doesn't seem to make any difference if it's 3 days or 3 weeks. I never had any issues with the good old stuff. I suppose I'll figure it out in time

Try a Euro clear coat. Not sure who ships your way but pretty sure someone does.

The stuff I'm using is a high solids clear, I just don't think they make it as high a solids as they used to. When I reshot a couple panels they came out a lot better. It's just a lot more finicky, way tighter sweet spot.

DA's spin to fast.


I was just looking at the manual for my DA and it's actually a random orbital not a DA. I just bought it recently after my DA died. I'll try it at half speed, thx.

Still getting lots of little circular scratches using the orbital, not pigtails just tight little circles. Would this be caused by the orbital running too slow or too fast?
I sand right up to 5000 trizact and you can't see any scratches even until you buff.
I went back to hand sanding up to 2500 and buffed, came out great but a lot of work.

The most common mistake with a RO sander is moving it to fast.
Not the running speed, the speed you move it.
Like the instruction manuals say, move slowly so it can cancel out the circles.
Nobody pays attention to that part.
You can't go back and forth like you would with a hand sanding block.
You have to move it slowly.
(Unlike shown on all the TV woodworking shows, they do it wrong)

Good tip, thanks. I'm working on the hood, last big piece to do. Hopefully I can get it right without resorting to hand sanding
