I'm rebuilding my transom with Coosa Board. I just have a simple question. Can anyone recommend a certain brand or type of Marine Grade Epoxy Resin that would be best when working on the transom or will any Epoxy Resin due? I don't know much about the different types or resins like 1:1 or 2:1 or 3:1.

Someone gave me a Gallon of Marine Pro Table Top Clear, High-Gloss, Epoxy Resin that is 1:1. Not sure if it can or should be used for this job. I obviously want to use the right stuff.

I don't want to use Polyester or Vinlyester Resin. I read that they don't adhere well to Epoxy Fiberglass surfaces.

I have a 16' Bayliner Capri 1989 Outboard

All deal with drying time and temperature. Look up u s composites, then select epoxy resin and into types. They have a nice listing and some reasons

Also blushing, if it does that it needs to be roughed up before another coat

Uhmm, your boat is not MADE from epoxy. It's made from Polyester resin and repairing it with the same will work just fine. Lot's less expensive too!!! Since Coosa Board is made from layered fiberglass it will be compatible with the Poly resin and everything will bond well. Having said all this, Wood transoms that are built, installed and maintained correctly will last many decades and will be hundreds of dollars less expensive.

Woodonglass thanks for that info. I did not know it was built with polyester resin. I already bought the coosa board $149 so I'll be going with that.

I actually have another small project boat that needs a new Transom and 1 coosa board is enough for both so the cost is not bad.

WOG is right on. If you can stand the smell, and can work within the time it kicks, polyester resin is cheaper. I find poly resins to be easy to work with.

Before you start doing anything start reading the many threads on this site about people making the same repairs, it will give you a much better insight on what to expect and what needs to be done.
