    Ask a Question

    By unpainted does it mean it's glossy white?


    • The RK Sport Fiberglass Rear Spoiler is offered unpainted. This will simply be a bare, unfinished product, and will require sanding, primer, and paint for a complete finish. This will come with a white gel coat finish which will be a low gloss white, and will not match any existing colors. Additionally the gel coat finish will not have the same UV resistance as paint, and will be susceptible to fading.
