re-painting hood question

I messed up on my pinstripping on the hood....long story short when I re-painted it last night I guess I did not clean it good enough (rookie mistake). I had several spots where it had pin holes or I guess you would call them blisters. Anyway the guy at the local paint supply store told me to sand it down with 320 then wash again, then use wax & grease remover & re paint.

My question is shoul I use some 2000 grit to smooth the 320 scrathes before I re-paint it?

Thanks SC

Basically no. Plus you don't make that big of a step in grit size. You could go over the 320 with maybe 400 dry or 500 wet. I don't know what paint you are using, but you should check the tech sheets for your paint and see what grit it recommends. Thats the grit you should get down to before painting. 2000 is a bit fine for anything. Some ball park grits for paint would be 800-1000 grit wet for areas that will only get a urethane clear coat. 500-600 wet for basecoat metallics. Single stage and solid colors of base, or if spraying on a coat of sealer, may get away with a little courser 400 wet. 320 dry is just a little courser then I personally like to go for basecoat, , specially if a metallic color, but many do final sand with 320 dry. Some brands of paint may have a little more fill then others, so check your sheets for what you are using for recommendations. The imron they use where I work has more fill then base I use. If this was done with base clear and you only have a spot or two with pinholes (the rest being good), you could sand those areas out or fill them with a glaze, and put a little primer over that area. Next day sand your primer with around 600 wet and the rest of the hood with 800 wet. Spray your base over your primered area, and once you start getting coverage blend the base out a little ways past the repair areas, and then after the base has sat the recommended time. clear the whole hood with 2-3 coats of clear.
