About to paint..give 2 cents
About to paint..give 2 cents I am about to pait the lower bumper on my ws6 black, ive already got the semi-gloss black paint, dupli-color Acrylic Enamel semi-gloss black
I figured i would sand the bumper down with 320 grit paper, clean it up well. prime it once, said again, wash it up. 2 coats of paint? what do you all recomend on post-painting finishing? should i went sand after a few days? I have painted bumpers before, but i want this to be done RIGHT. so let me know what you paint guys think. right paint? paper? ext.
thanks

why prime it? Is the finish you are painting on deteriorating? No need to prime and build up excess paint if the substrate is perfectly good. If you answered no to the second question then all you really need to do is wetsand with 600 grit and then go directly to color. The paint is relying on a good mechanical bond and spraying primer isnt doing anything for it unless the existing finish is bad.
I would only put on as many coats of black as it takes to get even coverage but also take into account that if you will be wetsanding and buffing out you will need a little more coverage to play with when sanding. wetsand with 2,000 grit and then buff out as you would normally on any car.

Stryker,
While I normally agree with all your points on painting, I have a question about painting directly over existing paint. I've been told that certain paints,especially 2K auto paints, can react with the exisiting paint and actually lift it up. That's why a primer or sealer is used by many people before a new base coat is put on. Have you heard or experienced this?
Asking this because pretty much everything I do is new paint to new parts.
