Default I'm going to paint a bumper- is adhesive paint promoter and paint all I need?

I'm going to paint a pretty beat up bumper, This is my plan...

Sand down with 320 grit sand paper
spray the paint promoter
then start painting??

do I need to primer even though I spray the promoter?

also is 320 good enough?

I'm going to use a gravity feed spray gun stage 1 paint

am I going to need to wet sand afterwords?

If I were doing it and the original paint was in pretty good shape, my plan of attack would probably be:

1 Wetsand with 400 or 600 grit
2 "piss coat" of adhesion promotor. You don't want to hose that stuff on, just a real light coat.
3 Sealer
4 Paint

Adhesion promoter isn't the same as primer, it's more like a glue than anything. Yes, you should always use primer or sealer of some sort. If the old paint is in decent shape (read: not peeling off and stuck on well) you can seal it and you'll be fine.

You might have to wetsand afterward. It depends on how well you can spray it on and how smooth you want it to be. Since you are spraying a single stage be cautious of wetsanding. If you are wetsanding a solid color it shouldn't be a big deal but if you are wetsanding a metallic color in single stage you can't sand very much because you'll streak the color.

If by chance you do get a lot of orange peel or runs just remember that you can usually wait 24 hours, then sand them out, clean it, and respray it.

My advice if you are a painting rookie is to spray test panels before you paint your piece, READ YOUR P-SHEETS (if you don't have any go back to the parts store you got the paint from and ask for some), and follow the time tables/mix ratios on the p-sheets to the letter and you should do allright.

Good luck!

I'd really have to see it to give you great advice just I'll try.

Sealer is sort of like primer but it goes on thinner. The purpose of sealer is to go on over the other material to seal off the other chemicals, as well as give a uniform base for the paint to adhere to.

For instance, if you fix a spot and you've primered the spot you'll have a panel that is half primered and half sanded original paint. You don't want high building primer because there is no more body work, you just want it all the same color and you want something for the paint to stick to. So, you can use sealer to spray the entire panel without adding much material.

Some primers can be sprayed as a sealer if you change the mix ratio. That is one reason I like using PPG's epoxy primer. You can spray it as a regular epoxy which will stick to bare metal and will fill some minor gaps. Then when you get the body work done you can use the same primer with about 10% reducer added to seal off all of that body work. And you don't have to sand it so you are ready to go straight to painting.

How bad is "not in decent shape"? Do you have any picture? If you are sanding it by hand I don't think you can go wrong with 400 grit wetsanding. It cuts fast but it doesn't leave sandscratches.
