Polyester Laminating Resin - Marine Grade Fiberglass Resin and MEKP Catalyst for Layups and Repairs (Gallon)

Worked well and gel coat bonded nicely to it.

This is a super thick resin that is supposed to coat boats. Boat decks, sides, whatever. I don't have a boat and bought it to seal my very old wooden deck. The cheaper sealers that one usually buys don't last two weeks, but this resin is like a liquid plastic. The value for the money is excellent because without it I would have to replace the deck. So it's a good buy. It is clear so the natural color of wood is enhanced. This is a terrific product. It's easy to use, except you'll need a bucket to pour a small amount in, then put the catalyst in just a squirt or two, then paint it on REAL quick. If you wait it turns into a hard, clear plastic. Use 2 pairs of rubber gloves, a brush and bucket you can throw away and only use outside. The smell is super strong, not great. You must work quickly with this and in very small patches, a cup at a time, it hardens so quickly. I love the protection it is providing. It might turn a little whitish now and again. However, my old wood deck is protected and looks great. That's my experience.

Worked good for large fiberglass repair on RV.

Good product as advertised. Could use a little bit more hardening Catalyst, though.

Had to replace the floor in my boat....this is great stuff...stays tacky between layers...
