1. What are the steps for application? Primer paint unsercoating? No paint? No primer?
2. Any discernable difference between bed liner and undercoating?

The only reason I’m against it is both my former and current dailies had the cheap spray can stuff on the frame and on the body with my current one.I'm interested in this subject as well for my 78. Why would moisture get under the bed liner anymore than it would with paint? I have heard that the spray-on traditional undercoat is porous, and will transfer moisture, aside from just flat wearing off (personal observation). I like the ideas of the bedliner being waterproof and noise reducing.
I had bedliner sprayed in my 2011 GMC. It held up very well. Snow, rain, nothing got underneath it and that was sitting on top for extended periods. In my opinion I cant see water getting up under it on the bottom of a vehicle seldom used.I'm interested in this subject as well for my 78.
