Ken, I will certainly check into that but I have a feeling that the size of my fuselage may be the issue. I think even the water putty will generate some heat while curing and the more you use the higher the temp. As I get closer, I will be investigating more. Even though I am an aerospace composites tech for a living, the technologies here are a bit different. My plan at this point is to have the plug prepped up with a splitter plate, well waxed up and a medium coat of PVA applied. I will then mix up some Klass Kote clear with some graphite powder and spray 3-4 coats of that mixture onto the plug. Next will be a mixture of epoxy, graphite powder and cabosil brushed on in about an .080 thickness. Once that gels I will do another layer of the epoxy/canosil mixture and lay down 4 layers of 1.4 oz cloth. That will end the first day. The second day will be 4 layers of 3.7 oz cloth and the third day will be 14 layers of 10 oz weight 8" strips run in 0-90-45-135-45-90-0 orientation twice. At least that is the plan as of now. I will be starting off with the wheel pant molds first.
