hello friends,
i am an enthusiast painter.i dont know much about secrets of painting.so i want to ask some questions about the proper usage of plastic primer.
after spraying plastic primer what is the ideal deal ,to let plastic primer full dry or spray paint over it while it still sticks. this is fundamental issue which i want to know about.
secondly i want to know if i can spray paint over it directly or i would have to spray regular primer first and then paint.and lastly i am confused that it would be right to spray middle section of steering which is indeed soft and seem to be rubber.i wonder that after spraying, the paint would not crack by pressing that area.
I don’t understand your question,are you asking about an adhesion promoter for use on raw plastic or painitng a rubber steering wheel?There are a few choices.
the paint store near me have one product which is called plastic primer.the store keeper told me it is used before paint.as you cant spray a plastic without it.so all my queries are about this particular product.
Do you know the exact name of the plastic primer? then we could help you out a bit more
adhesion promotor has to be applied to bare plastic than let flash for 10-15 mins ,apply sealer with flex additive, base coat than clear with flex add. thats how my paint rep. warranties my work anyway…
I use sprayable bull dog in all my bare bumpers. I clean the plastic with hot water, dawn soap and scuff. Then spray a light coat of bull dog, let flash a few minutes then one more full coverage coat. I let that flash for 10-15 minutes, then spray my base coat. You really need to let it at least be tack free, if you don’t it will never dry or set up under the base/clear and will lead to huge problems down the road. I dont use flex agents, by the time it flexes enough to use it, it’s done more damage to the clear and needs refinishing anyway….
that makes no sense to me. why dont you use flex add. in your clear? i have experimented with the stuff and taken plastic bumpers and folded them in half and had no issue. the stuff is warranty in itself.

cuz jay told me it was built into the clear :weights :weights :rofl :rofl :roflI don’t use it either, it eveaporates out after a year.
Adhesion promoter is itself a flexing agent to some degree. I use so my paint doesn’t flake off, that’s a warranty issue. However, say I paint a bumper and the customer bumps a car in a parking lot six months later and spiders the clear. How would this be the printers fault? Even if it broke off some clear, the driver hit another vehicle. So in my mind it’s not a warranty. You also want repeat customers, not saying rip them off with a crappy paint job but if it’s bad enough that they (or you) think it’s a warranty issue it was bad enough to be re finished. Again, do it right and it’s the customers fault for hitting something….
