Does your gas tank sealer work on plastic and fiberglass tanks?

Does your gas tank sealer work on plastic and fiberglass tanks?

Yes.

To apply gas tank sealer on plastic or fiberglass tanks, take a handful of drywall screws and shake them around inside the tank for a few minutes. This roughs up the surface of the tank, providing best adhesion for the sealer. Follow the mixing and application directions that are printed on the product.
