While making my first mould I ran into the problem that the gelcoat was repelled so much from the Easy-Lease-covered surface that it was very hard to get the whole surface covered, once painted on the gelcoat would slowly develop bigger and bigger holes and basically pool in the lowest spot, even though that it wasn't thin at all. It took about three applications to get acceptable coverage that was still very thin in some places. I knew that it wasn't tooling gelcoat, I couldn't afford to order any right now, so I used an epoxy gelcoat that I had. Basically I guess that it just wasn't a suitable product for this application, but can I be sure that once I get a proper tooling gelcoat for future projects it will not sport the same behaviour?

Kind regards

Thanks for your input, what you describe is basically what I did, but the gelcoat I used still produced fisheyes when it was hardly brushable anymore but after three coats I got finally rid of all of them. I think for now I have to wait and see what happens once I get another product.
