resin or epoxy for transom

[chrisvazquez1]

im rebuilding my transom and im using 2 1" pieces of plywood. called boat builder central today to order some filler. the gentleman informed me that the best filler to use as a glue would be wood flour because its not as "brittle" as silica/cabosil. he also told me that he did not recommend using resin because it woudl eventually peel off, maybe in six months maybe in 3 years but eventually would literally peel off. ive heard great things about poly. resin and feel comfortable using it but would just liek to know if its suitable for a transom rebuild. also, wht type of filler should i use with resin?

Do you mean what type of resin to use to glue the plywood together with?
Epoxy is the only way to go for gluing the ply together.Polyester would not be good in that application.Personally for a thickener,i like cabosil to thicken epoxy resin for gluing applications.I've done a few transoms and never had a problem with it.

AS for the polyester resin,i would't try to use it for gluing the plywood together.It's not flexible,and it does'nt adhere well enough or sink into the woody,like epoxy does.Go with an epoxy resin.

BoatBuilder is giving you good advice. I would use epoxy, and I would use wood filler, the cabasol/silica is VERY brittle and hard, and will crack. I used woodflour for almost every thickening application.

I used woodflour for almost every thickening application.

HaHa....so does (did) Breyers Ice Cream! Or at least they used their rail cars to load it at the lumber mill I worked at.

spoke to smurf over at mirage boats today. he recommended using "gp" resin. its not as expensive and is a better quality resin. anyone have any knowledge of this?

can't help you on the "gp" resin, but I will second what the others said - Use Epoxy resin, not polyester resin, when doing your transom. I might suggest, in-between the two sheets of ply, to also use a sheet of matt glass, well soaked out in resin.
