Vinylester resin is safe for use around alcohol and alcohol related substances. My whole airplane is made from vinylester. However, vinylester will NOT adhere to any epoxy layups. So, don't try to put it on top of any other epoxy resin types. I believe (with emphasis on "believe") that vinylesters will adhere to polyester resins. Vinylester was originally formulated to make underground gas tanks.
