Here is my problem. Let me start out by saying were talking about a car that I'm going to sell for ONLY $3500 NOT a show car.

I've got a car I'm selling, and the top surfaces are all horrible. Looks like someone took a razor, and went up/down the surface a million times.

Of course its just the factory paint starting to die from neglect [not me].

Here is my dilemma. I don't have time to do a show car type paint job on this car. I took the paint down to the factory self etching primer on the hood, and still have gaps where I went through the self etching primer with my sander.

I don't have time to go all the way to the bare metal, but I've painted enough cars now over 30 years to know that even with a couple of heavy coats of Nason 2k primer those gaps through the SE primer is still going to show through the new paint. [of course the car is black].

Here is what I was thinking. Would it work to just mix, and apply the Nason 2k with a brush vs spraying it on?

This way I would get a much thicker coat, of primer which should [in theory] fill in all of those gaps where I went through the factory primer. That way I shouldn't have as much finishing sanding to do, or coats of paint with the spray gun [where lots of the primer will be wasted into the air].

Also, the top of the car is the same way. So, I don't even want to go past the factory top coat of primer, BUT the cracks are going to still be in the primer. Again, I was thinking by applying the primer with a brush it should fill in those cracks vs spraying.

Once again, while I want the car to look decent [single stage Nason urethane paint] I don't have the time, nor can I afford to go all out. Plus its hitting 95 degrees out here so I have to shut down before noon.

Anyone tried this? Opinions? Thanks.

Here is a pic of the hood before I started stripping. [the top is similar, but I can't stay up all night waiting on Imgur to upload].

I could sand the hood, top and trunk lid down to bare metal have a cold beer in about an hour what are you using to sand it with? if your using a da hopefully a 6" lock the orbital out and put some 36 grit on it and go to town. it will be much easier to just sand a little further to bare metal rather than some hokiest pokist way that may not work.

I''ve been using a straight line sander with 36 grit.

Also a grinder with a wire brush.

do you have a DA sander ?

I do, buts old as in 1980's old......lol.

IIRC it ran my compressor to death. My compressor is 60 gal/5hp. I do have two smaller compressors I'm thinking about joining together to take the work off of the one big compressor.

So a good DA sander would make quick work of all of this?

it would be better than the straight line sander your using, IF you can lock out the orbital mode. with 36 grit paper on a 6 " pad it should go quite fast theres nothing wrong with an 80s sander if its in good condition put a couple drops of oil in the air inlet before you put the hose on. just a couple drops you don't want to spray oil all over everything
Jay D..

Ok, thanks I will give it a try.

FTR, I don't mind stripping a car down to bare metal if its an old Mustang, or something valuable, but for this car it just isn't worth the effort.
