looks like you have the right idea now jimmy, get at er!
Block sand block sand block sand, then sand some more. Wondering what grit papers you are going to be using along the way here, (pre primer, on primer, pre color, ect)

I used 120 to sand off the old paint. I will use 120 to block sand the primer then primer again. I will then use 320 to sand the primer for paint.
Thanks DeLorean.
I read through your thread 3 or 4 times while I was doing research on painting.

The underside of the hood is now primered. When that dries I will flip it over and primer the top. [This message has been edited by JimmyS (edited 01-12-2009).]

Unless you got HUGE gouges I'd use 320 and 400. then wetsand with 600.
you'll get a better finish.

Wont 600 be too smooth for the paint to stick properly?

After your last thread about compressors, I'm glad she went the Hausfeld route. Good size and pressure. Painting is the most fun part of the car so enjoy

Mine was meticulously sanded with 600 for MANY hours, using squeegees until it was 100% perfect, and I know it was worth my time to get every last little scratch out.
Honestly thought the 320, or 400 wet (400wet cuts the same scratch 320 would) would be more than enough for a high metallic colorful paint job, as those small swirl scratches would not show on a brighter metallic color. I sprayed black, and I had the time to do the extra mile on the prep, so I did all that I could to make it perfect.
There is no issues with adhesion from the 600, mine was shiny as glass before I sprayed with sealer / color. A good sealer should be specifically designed for a 600wet scratch, mine wasnt and I had no issues.

600 wet is perfect before colour. Industry standard over here to use it. Also a light black guide coat wouldn't go astray to make sure you get it dead smooth.

I sand 320 and 400 dry to rip through the rougher spots and then wetsand it with the 600. 600 CANT dry sand as it will clog up fast.
Be sure you are allowing the right time between coats. If you are not in a hurry, give it a day between coats. I had to fix some wrinkling in a couple of spots because I listened to the can and did a recoat on the sealer after 20 minutes like the can said... when I sanded out the problems and re-sprayed to fix I let it sit 1 day and then recoated with no problems.
Dont rush, and wipe with a tack cloth before every spray no matter what.
