> Only if they are designed to be mixed 1:1. Epoxy formulation has become rather sophisticated over the years. Epoxies are now available for many different and specific applications. The epoxy I'm using right now is designed to be mixed at a 1:3 ratio. I've used other epoxies that were designed to be mixed at a 1:5 ratio.

> Best advice I can give on epoxies is to find a manufacturer you like (or whose products are readily available to you) and stick with it. Learn its characteristics and how best to work with it. Most of the major brands formulated for use with wood (look for suppliers to the wooden boat industry) are excellent. Most of them also have handbooks available to teach you how best to work with their products.
