Gas tank installation

[cc]

I have built a couple of new aluminum tanks and had them sprayed with bedliner material. Have had no problems. I did put them on thin (1/4" thick) ribbed rubber floor runner to take up any uneveness of the tank floor so the tank wouldn't chafe while being bounced around. The bedliner material is safe for aluminum and is impervious to salt water, chemicals, etc. Any body else done this???
