You know the ones I mean, those little @#$%^& black dots that are on the top of the rails and that will come out with a good pressure wash.

Is there any way to seal them up so they don't catch dirt?

I know it's a cosmetic thing but it bugs me. lol

I'm thinking of attempting a little test here with my boat, I figure I'll pressure wash a patch so it's clean and then take a heat gun and see if it will "flow" the surface and seal the pores... Your thoughts about this???
