a while ago I read a post about using truckbed liner to waterproof floorpanels. I was thinking about using it to waterproof my floor and also my trunk. I was thinking that it would also help make sure that nothing would puncture my gas tank. Is this a good idea or not? If you put it on, is it there for good or is there anyway to remove it?

Its pretty permanent stuff. I wouldn't do it just because any future rework would be a PITA.

If the metal is good, just go with an epoxy primer and topcoat. If the metal is bad, well....thats a whole 'nuther problem.

sounds like a pretty good idea to me, i would mask off or do something to make your the bolts holding your gas tank in don't get covered, maybe take the tank out and do it separate, hmmmm seems like it would be great sound-proofing as well........ i'll keep an eye on this post,to see what others think.......

If you want to protect your fuel tank, then I would recommend www.tankarmor.com instead of the truck bed sealer. Also, they make a good splatter paint which gives you the same look I think you are trying to achieve with the sealer but without the down sides.

Truckbed and rubber undercoating is good to reduce noise and also keep water out. I did my whole trunk in rubber undercoating because it was cheaper than the truck stuff. In the car I used Dynomat and where I couldn't stick it I used the coating again. Great stuff. It gets less heat in the car and also my stereo will not rattle everything.

I like the tankamour that dnbventures posted. If something like that is in your budget, that would be the best idea. I did use Walley World truck bed liner in a spray can to seal up those front fender splash shields. The stuff seems tuff as nails. I'm debating whether to use it in the wheel wells and insides of the front fenders instead of rubberized coating.

does the rubber undercoating stink when it gets hot? I was thinking about that too, that it would provide more padding for the gas tank than bedliner, but I heard that it can be a mess and gets smelly when it heats up.
