i just got my replacement bumper and am unsure of the process. its raw urethane unprimed. do i need to use an adhesion promoter, such as that bulldog **** i can grab at the store? or is there a flex agent that should be added to the paint? i've painted lips before and the paint has just chipped off, but this is an entire bumper and i dont want it to look like **** within a week. help is appreciated

 

I would just put the "bulldog ****", then apply basecoat followed by clearcoat.

 

How did you determain the bumper is raw plastic?

Refer to the paint brands specs on how to paint raw plastic. If you buy the paint from a distributor, they will provide the info and should be able to give you detailed advice on how to prep, paint raw plastic. Adhesion promoter and flex addetive should be used, but I recommend using the same brands/ paint system products.

Steps for painting raw plastic bumpers:

1. Bake the bumper (heat causes the oils used in the mold to surface)
2. Wash the bumper
3. Scuff the bumper (scuff pad with bumper prep sanding paste, or fine grit sand paper)
4. Wash the bumper and dry it
5. Clean the bumper with raw plastic cleaner
6. Spray bumper with an adhesion promoter (same brand as paint you are using)
7. Spray bumper with primer sealer (not everyone does, but I do)
8. Apply 2-3 medium coats of base
9. Apply 2-3 wet coats of clear

And yes you should use a flex additive. These are just my steps, everyone does it differently, but that should give you a general idea.

 

exactley what i was looking for. thanks dude

 

x2 the steps above except i don't use flex additive. You really don't need it with the modern urethane paints. I also use a reduced epoxy primer before the base.
