I have been messing around with a 2 part mold for a large 9 inch swimbait. I started using Smooth-On product, but had serious bubble issues. I also tried Alumilite Amazing Clear Cast, filling one half of the mold, allowing it to degas for 30 minutes, then applying the second half of the mold. The excess casting material oozed out of the vent ports. this worked excellent, but the tensile strength of the material is very low, when compared to other casting materials. I wanted to try Alumilite regular, but unfortunately when I went to the local Hobby Lobby, they last bottle in stock was already gone. I went to the Hobby Lobby online store, and can't find it there either. maybe they are no longer carrying the product. Which is unfortunate because of the 40% discount coupon they offer. So, my question is, will I have the same bubble issues with a fast drying resin like Alumilite regular as I did with the Smooth-On product? Does anyone know of another hard resin i could use, that has a slow cure time that would allow me to degas the resin as described above? Or, do I just need to keep playing with my mold until i find a way that allows all the gas to escape? Thanks-
