He's talking about a wax addtive to stop the gel coat from being tacky, so what this additive exactly is, where can I find it (doesn't seem to be sold in the EC store), and which is the ratio to be mixed with the gel coat ? Thank you guys

Thank you guys You can use a chemical as Warren has said. Over here we call it "airdry" Its a paraffin wax suspended in alchohol. A trick I use is to just smooth over sandwhich plastic wrap over the repair while still wet. The outer surface of polyester will stay tacky if cured without sealing by one of these methods. That is a good thing because your next layer will chemically bond as one with the previous layer. The plastic will peel off clean and the resin will be completely cured to the surface. (because it is not in contact with oxygen) Hope this helps. Fred
