I have used a thick coating of axle grease, but I would not do that if you add a lot of catalyst or cast it where it when it is very hot out. Only stuck a couple of minor places. I also used some wax, actually from an old plumbing sealing ring, and that worked pretty well also. I put it on so thick, and did not smooth it out too well, so it did leave a bit of texture, but otherwise it was functional. Just some ideas. Rich
