Epoxy vs Vinylester

[dbiscayne]

poly & vinylester are fine on a new build, when laminating wet on wet layers of material, but you'll never get as good of a bond onto something thats already cured. Thats where epoxy has such an advantage, a great secondary bond. It's also easier to mix, doesn't smell as bad, & has a longer working time. But you can't put gelcoat on top of epoxy.
