A friend stopped by to get some welding done and other things. He pulled out a gallon of Plasticoat Bedliner. He is going to use it for underbody sealant instead of POR15 or paint. Has anyone ever used it before, it is only $35 a gallon and alot cheaper then Rino Liner.

You get what you pay for. I've had problems with it peeling off in large sheets. I've seen some other trucks do the same thing. There's no short cut for quality. Invest the time and do it the right way.
