TWO QUESTIONS.......WHEEL WELL FINISH AND FENDER INSTALLATION

Hi Folks

Just getting to the final stages with my '71 Demon and I have 2 questions.......

During re-assembly, is there a sealer or gasket that goes between the inner fender flange and the underside of the fender mounting boss, or does it just get bolted on?

Next question........Here's what I did........I epoxy primed the inner fender area (front and rear wheels)and splash guards, then applied paintable rubberized rocker guard. Now, should I paint that black, or body colour?

Thanks FABO
