I was reading some of the old threads on varnishing the wood parts. The case being that they will not be assembled until much later and need some protecttion.
The suggestion was to use an epoxy based varnish that was compatible with the epoxy based adhesive to be used. Then it would not be necessary to mask off the areas to be glued.
I know that there are different types of epoxies for different applications, each with different properties. So my question is, how does the layer of epoxy varnish in the glue joint affect the strength of the joint, even if it is 'compatable'? Would it prevent the T88, for example, from penetrating into the wood? Is the compatable varnish as strong as the T88? Is some type of surface prep of the epoxy varnish needed before using the T88?
