great stuff thought

[SW86]

well ive had the por15 and got the good weather to do it today. i was wondering about something while looking at the cab. the holes in the floor (not the drain holes) i was thinking about filling with tuff stuff and then going over with the por. has anybody done this or thought of? any draw backs? i know water will eventually get in the cab and figured this would help keeping it out of places i can't reach. comments welcome, thanks

 

 

edit:

 

i mean Great Stuff Foam, not the tuff stuff car cleaner haha

Seems to me a good way to keep wet and damp in, provides for places that rust loves. I recommend not doing it.

well i mean its waterproof and right now the cab is bone dry with no rust in it. plus once the foam expands there will be no hiding places in there and the POR top of it should make sure nothing ever gets in. only way is through the bottom but i doubt it'll go down like that..... i might not do it anyway just because and just get down the POR first. i can always go back and fill it if i wanted right :D

if you have ever had a rusty floor board, guaranteed the sheet metal holding that plug inside that rail is rusting all the way to the back,

a reason why i want to re-design my rusted frame rail, take off the old one, chop all the rusted stuff out and throw cocacola over it :D

and put new stuff in :hijack:

 

lol trust me, there is alot of room in there XD i shoved my whole arm down it, so be carefull when you use the foam

it's a good engineering rule of thumb to assume that water will get everywhere and plan accordingly to deal with it. :thumbsup:

 

plus that foam stuff attracts moisture and accelerates rot. :( ask my 88 about that. :fs1:

The very first thing I do when ever I get a new Jeep is to take a air chisel and cut the floorboards out. No floor board, no rust. :popcorn:

Exactly right, Great Stuff absorbs moisture and retains it. I learned that the hard way on a couple of in-shore fishing boats I rebuilt a few years ago. I can't recall the name of the stuff I'm thinking of but there are several products for the marine industry that will expand enough to completely take up the space and keep water out. Despite what the label says it's not a good waterproofing solution. Look for stuff made to pour into boat hulls if that's what you want to do.
