For the wood, what kind of clear finish should be used if not varnish or polyurethane?
Dirtwheels-The sytucture will be primarily plywood. Other than joints and tabbing and such, It seems the glass is really more of a protectant service rather than a structural issue.dbisquane- is that a coating like varnish or a treatment like oildburr- The majority of the wood will not be removable. Some of it will be exposed to the elements. Originally I was going to go with a resin coat and then multiple coats of clear, but i heard the resin will yellow badly. The wood will be heart cypress, teak, or mahogany.
