quality is key, both in product and the application. I paid to have my rockers Rhino lined many moons ago and they turned out crappy. but once done, there was nothing I could do about it. they had drips and the guy plugged all my rocker's drains. but I've seen some well-done examples these days too. Monster and Raptor are light years ahead of Rhino.
you have to want it though, as there is no going back.
