Thanks and no I didn't know the tricks. I use contact cement for a lot of things but until I read Lou's build thread the thought of using it as a canopy glue never crossed my mind. I have always just used standard old canopy glue and tape. If done correctly this is much better and stronger. If not done correctly I can see a bunch of problems and a big mess. I lined everything out and used a small paint brush to lay the glue down with so it was nice and neat, unlike my usual work and have been very pleased with how well it has worked out.
For the cowls a friend wrote me and reminded me about just using a soda bottle and heat gun over the plug to make the cowls. I have done that for making canopy's but never a cowl. I'm going to try it but I worry about the heat melting the foam plug, it's pretty big. I once melted the foam plug when using regular resin to lay up the glass, the heat of the resin curing caused a big problem. When I made up plastic canopies I made wood plugs so there was no problem. Melting/shrinking the plastic instead of doing a normal glass job would be like hitting the easy button as long as the plug doesn't melt. Worth a try though. This stuff keeps me out of the bars and strip clubs so the wife is all for trying it! Not too much work if I have to make a new plug.
