Drew Sailbum:Uh, I´d skip the Rhino Liner stuff. As a certified tank inspector, I´d hate to have to have your coating stripped off to look at the underlying metal as a routine part of the visual cylinder inspection. Absolutely no chance I´d approve a cylinder without seeing that metal surface.
I was going to mention the same thing. Rhino lining and any type of plasticy coating looks cool, but you can't tell what's going on underneath. Most trained inspectors will avoid approving those tanks.
