I've used JBWeld Aluminum on the spars with good results.
You don't need epoxy on the wood. Just find a varnish you like and read the directions. If it recommends a thinner, thin it 50/50 for the first coat. Some brands have wood sealers also, basically thinned varnish, for the first coat. Check your big box store, they may sell Rustoleum wood sealer and varnish.
