    Oh that word that seems to haunt all we do!

    Where will these be mounted as to be subjected to "road debris" (stones & sandblasting?)

    Second concern would be what did you intend to refinish them with; a gloss, a texture, or ? It all matters as I've seen people who absolutely need these coated properly to lessen damage yet others who finish them off on some show machine with a 90%+ for show only.

    Keep us posted and take care!

    That seems a very doable area for refinish in nice gloss paint. Take a look at those type bumper arrangements and that area does not seem subject to direct impact of stone/sand. What type of paint are you thinking?

    Take care!

    We would sand down the scratched areas until the scratch is gone but extend the sanded area so that you don't have a dip where the scratch was then apply a filler primer over the low spot and apply a light guide coat, allow the primer to harden then block sand with some 600 wet. Use the same sandpaper to sand the entire piece then paint.

    As long as the plastic is sanded with around a 220 or 320 grit sandpaper then the primer should adhere well. If the plastic is flexible you should add some flex additive to the primer.

    You may be able to use that, I'm a fan of two part primers with a flex additive mixed in.

    We use High TecK filler primer and activator. We can have it shipped to you but you may be able to buy it locally. We sell High Teck for $29 per quart for the primer and $40 for the activator. For a flex additive almost any brand will do a decent job. A decent primer and the flex additive can also be found at "The Coatings Store" linked from the banner at the top of this page.

    We rarely check the type of plastic, we use a decent adhesion promoter on a sanded surface and a flex additive in the clear or single stage paint.
