I would recommend getting a quart of the Proseal from Vans. It is the most economical method and there won't be a rush to get everything done at once. I bought a piece of oak board from Lowes. The board is perfectly straight to weight the longer elevator down. I used a premium grade 2.4 for the other elevator. They are straight as can be. The proseal wasn't that hard to use. Multiple gloves and a daughter willing to lift the skin was great!
