The best low tech release is Kiwi. I will not use Pam or any oils or greases as they make for an ugly job which someone is paying for, not to mention that any thickness of release will make for a loose fit. I have tested Kiwiand it works well although for production I use a real release agent that I buy by the gallon, it is a wax as well. Look out for anything with silicone as that can cause real problems with paint down the line. Epoxy adhesives do not generally make the best bedding compounds. They tend to be a bit rubbery so a joint will flex instead of breaking. I use Marine Tex for bedding. It will stick to metal fairly well and to composites or wood as well as anything. It has been tested for shrinkage etc many years after installation and it holds size and shape better than Devcon does. Funny because they are made by the same company.
