expanding foam

[angrysnowplow]

Anyone use this stuff to slow the rot down? I'm in the middle of my tailpan project and was looking for something for behind/below the tail lights. /forums/images/graemlins/thinking.gif

I saw some expanding foam stuff on monster garage, they used it so they could make a VW beetle to float. I don't have a clue where to get some though

I've used it in trunk lids to quite the rattles the subs tend to cause.

it make make your rockers more sound, I used it in my rear panels behind, above and bleow the tail lights to make it ridgid, as for rust it wont be foll proof but may help a little. /forums/images/graemlins/thumb.gif

You can get that stuff at any hardware store....comes in a can...

I would think that it might hold water in there longer /forums/images/graemlins/dunno.gif

Maybe just coat it with POR 15?

I dont see any way that it would slow down rot do to the fact that it's so porus and would be like a spounge.

Might hold the rust in place, though! /forums/images/graemlins/waytogo.gif

DO NOT USE IT! This foam will eventually HOLD water and completely destroy everything, unless you spend the money and get 2 part closed cell foam used for marine applications. The "Great Stuff" foam-in-a-can isnt a good idea.

It'll hold the moisture against the steel and make it rust faster and more thoroughly. If you look at the rust prone areas on our trucks they all share a few things. Poor ventilation (ability to dry) and poor drainage (trapping wet debris against the steel).

The expanding foam in a can does retain water...

What I used on the inside of my doors and tailgate was the spray on rubberized coating. It will come off easily but it should keep the water away from the sheetmetal in places that aren't exposed directly to the elements.

I'd say Rubberized undercoating would be the best product!!! /forums/images/graemlins/peace.gif
