Dan and netters Opinions are good, but when it come to a product, people's opinions can change someone choice. I work for a company that started out as a builder assist company for Glasairs. Glasairs are made of VE, our new owner has worked for the company for 15 years, and he hates VE. I have and old KR and used VE a little rebuilding it. I really grew up using VE, due to my dad using it for his projects. I work mostly with Epoxy now, but if we have a project at work that is VE I get it. My recent history with VE would freak most people on this net out. I have layed up parts in a mold that would use 7 gallons of VE and we would do it all in 2 hours. I disagree with the statement that VE has a film. The reason you can't lay Polyester resin ie VE over Epoxy is the wax that comes to the surface. Epoxy can be put over Epoxy without any prep within 24 hours. With VE you need to scuff the surface. Peel ply is a different story. Health wise Epoxy is worse for you. Lungs, touch etc. it all comes down to personal preference, are Fords better than Toyota?
