Looking for a replacement solution to the original fuel tank pads that retain moisture and rust the tank from the outside in.
Was thinking about some type of rubber padding that may be used similar to the below. Would also like to line the top of the battery tray with it as well. Any thoughts? Waxman 2-Pack 4-in Black Rubber Pads (w/ adhesive backing) |

I know i'm speaking alone here but I have serious doubts that a neoprene pad is solving the problem of moisture being trapped against the tank surface. It is just trapping the moisture it in a different way. If the surface of neoprene or rubber is textured to minimize the contact area with the tank, I think that would be ideal. Another option might be to smear the pads with a sealant just before dropping the tank in to prevent water wicking between the surfaces. It would be easy enough to test a neoprene pad by placing a piece of glass with a little weight on top and then spraying water on the edge so you could see how much wicks under the glass and how long it takes to dry.

I agree completely. If your felt pad, or whatever pad, is getting wet....you've got bigger issues. As long as your trunk seals are in good shape, why would you be getting water in and around where the felt pads lie? That part of your front trunk should be "bone" dry. If not....

(IMG:style_emoticons/default/dry.gif) I guess I'm going with the assumption that it will get wet, but does seem like the pads on a car with good seals should stay dry. It occurred to me though that condensation on a metal tank full of liquid could be an issue and where neoprene would be a big improvement over standard felt since the neoprene would insulate the tank at those spots whereas the felt would just soak it up and hold it. Regardless, I still think the best pad would be a non absorbent cushion that is well ventilated. |

QUOTE I guess I'm going with the assumption that it will get wet This raises a question. Why should that area get wet??? Do you have leaks? Maybe it's more about what absorbs moisture. If you have water getting in there, that's another problem. Seriously, it's about what TRAPS moisture. Which felt does and neoprene does not. |

My car spent most of its life in the PNW specifically Portland/Seattle and was for the most part rust free. When the tank was pulled it had enough corrosion to open up some pin holes upon media blasting prior to powder coating. This is what I was dealing with. Whatever caused it, I have no idea. Here is what it looks like after paint. |
