Protectant/appearance enhancement for fiberglass top?

[Digitalchaos]

After washing, paint cleaing, & quickwaxing my black Jeep I noticed the fiberglass top looks a little dull in comparison. I have been looking for a product to apply to the exterior rubber, vinyl, plastic, ect surfaces for enhancement & protection, and wonder if I could get something that would also work well for unpainted fiberglass, a Jeep hardtop.

This must be available at a local store like Napa, Autozone, or Walmart.

Any suggestions? Thanks for any assistance..
