I'm considering using Durabak as paint on my 60. This is pretty radical, I guess, since after I did it there wouldn't be any turning back, at least not easily. Anybody else done this to a 60/62? How's it look? Does it fade much? Regrets? Also, what about Durabak as an interior tub liner? How does it do for sound deadening and for durability? Is Durabak better than Herculiner?
