What is Gelcoat and Its Importance

Gelcoat is a thermosetting polymer that consists of polyether resin or epoxy resin. Information technology can serve as a topcoat applied to the fiberglass boat's surface, and almost all modern vessels with this hull blazon accept this gel coating.

The cloak-and-dagger is to apply Gelcoat in liquid grade over the fiberglass surface in a thin layer from 0.02 to 0.03 inches (0.51 – 0.76 mm) and let the coating course a wrapper around the hull during drying.
