I used MinWax Spar urethane in the rattle can for nearly 6 years. Spar is cheap, requires no spray equipment but.. You have to seal up any oily woods before adding finish, it can dry in 6 hours in the right conditions But takes at least 3 days to cure and you better wait 7 days before dancing out any runs...In February this year I started using Krystal Dull and Gloss from Big Jim. The Krystal drys in about 20 minutes, I believe you could sand out any runs after 20 minutes..I had to buy a 26 gallon compressor( bigger would be better), inline filters, a mini HVLP touch up gun that I had to make a 1.4mm tip for, hoses, etc...so far I am very happy with the Krystal its an improvement over the spar.. but I know T-Bird or Big Jim's Buffalo Hide is a better, tougher finish. One day I will give it a try. I always wanted to try a "Massie" type Finish" but never have.
