Group: Forum Members Posts: 13, Visits: 332	Hi there I recently made some moulds made out of Vinylester/CSM. The gel coat is Polyester based. So now the question is... ...how long do I have to wait until I'll be able to use the moulds to build composite parts? Btw... ...I'll be using ECs GC50 gel coat combined with epoxy resin on the composite parts.

If you have spray equipment why not just spray a clear gelcoat like GC50 ? that way you can use easylease without the addition of wax, which to me defeats the object of using the chemical release agent in the first place. Regards Warren Hi Fred, sorry if my statement above sounded a wee bit harsh It wasn't intended like that. We are all learning/finding techniques that work best for our given situation. I am now doing this full time and have to try and come up with ways to maximise my profits/income. Using the GC50 has really improved things for me. I try and get 4/5 moulds prepped with easylease and then spray them all in one go. Another thing I like about it is that after about three hours it is tacky enough to act like a spray tack. I can lay down my first layer of carbon into the moulds and it is held in place and nicely aligned. I can then continue with the rest of the stack on all the moulds at a more relaxed pace ready for infusion. The GC50 also gives me a hard glass like UV resistant finish straight from the mould. Previously I had to flat sand and use a 2K Clear to get the same results, much more time consuming. The bond between the GC50 and the Epoxy is far better than when I was using the 2K Clear. Nice to hear that you have a technique that works for you Regards Warren Carbon Copies Ltd

I didn't know this GC50 had UV resistance. I will have to look into it. Do you get any beading or fish eyes when spraying it? Fred
