I have a damaged front bumper.
There's a 4" by 1/8'' gash.
I repaired (filled in) the gash using a plastic bumper repair kit.
I then sanded it flush.

Question :
Do I have to prime the filler and the plastic around it before I paint it?
There's about 25 square inshes of plastic around the repaired gash that has to be painted as well.
After I paint it, should I use a clear coat over top of the paint?

I have colour matched paint (black) to paint with.

Thanks
Walt

Any bare surface needs to be primed/sealed before paint...

and... errr... if you cheap out and use single stage paint it does not need clear (bad idea... doesn''t last too aweful long)... if you do a base coat/clear coat... then yes of course
