I have two coats of single stage R-M Uno on my 68 Porsche restoration. Had a few mild runs that I got out with a hard block and 1000/1500. Quite a few dust nibs.

I've watched a lot of videos about cut and polish, but they are mainly on base/clear where you have more to work with, or if single stage they're talking about refreshing old paint. I don't have a lot of experience doing paint correction.

As a (70 year old) beginner am I better off with a DA or a sander polisher? I understand that the DA is a bit more "forgiving", but may not be able to do the work that a sander polisher can do.

If a DA, do you need to use more aggressive compounds?

Am I correct in thinking that I should flatten all the dust nibs one-by-one wet with 1000 or 1500 and a small block so the block cutting for any orange peel can go faster before using either the DA or sander polisher?

Many thanks for any advice.

Are you talking about a solid color Single Stage paint?

I would not take a chance on sanding out runs if I only put 2 coats of single stage paint on the car. You'll wind up sanding through the surrounding area.
As for polishing, DA type polishers are more gentle, easier for beginners. Take longer to do the job. Rotary types are more aggressive, better for people with experience.

Thanks chopolds. I was able to sand out a few runs with no problem. (Well at least so far- time will tell after blocking and buffing.)

Coronet- yes, solid color. Burgundy.

Might be better to sand it flat and shoot another coat or two?

Well the paint cost $1500 for a gallon so I'm gonna try and not have to do that. Tech sheet said two wet coats. I did respray the driver quarter panel after three tips of a sag came off down to the primer when razor blading. I stuck to sanding with a firm pad after that and it seemed to go well.

I bought a short throw 6" random orbit DA sander polisher and the Griot Garage 5" conversion kit with backing pad and five pads. I figured that will keep me busy and hopefully out of trouble.

Yikes! Is that Burgundy made out of gold dust?

Something like that- it was painful.

R-M Uno HD, burgundy- $983/gallon. Quart hardener- $253. Including 15% off list. ouch.

Do you have the paint code for it?
I would like to see what my supplier would charge.

1968 Porsche, 6808 Burgundy, single stage.

The cars were originally painted with Glasurit, but I think that costs even more than the R-M.
