Sealant on top of a restained fiberglass door?
What kind of water based sealant can I put on top of a restained fiberglass door?
There is none… use an Oil base sealant…
Actually there are several very good water-based clear finishes. Varethane Diamond Spar Urethane is a very good clear finish. I use it all the time for fiberglass doors. Other good manufactures are Zar and Old Masters.
