I stripped my pumper all the way down to the ployurathane. It is just yellow. I do not plan on painting it right now, is it safe to leave it the way it is or should i spray primer on it. I wasn't sure if the sun would dry it out or hurt it. Anyone know where I can get flexible bumper filler? I have a couple spots that are scrapped, so need to fix it. Any ideas?

 

SEM problem plastic repair will do nicely as a filler, get it at a paint supply store. I would prime it just to keep bugs from embedding themselves into the plastic on impact when driving.

 

Should i buy that stuff first then prime it? The primer i got is clear, is that allright?

 

Yes, use the SEM first, it needs to bond to the plastic.
