+x Warren (Staff) - 9/26/2018 3:01:39 PMIf you are just coating over the top of the coasters, then the GlassCast 3 is the better choice. For thicker castings around 10mm or so or for pouring into a coaster mould, then I would go for the GlassCast 10. Both are easy to mix and use but with slight differences in clarity and surface levelling. The 3 is smoother but less clear than the 10. You can find both the resins here: Epoxy Resin
