Well when I bought my '85 4Runner a few weeks ago I could see that the rear fenderwells had a little rust but I didn't know to what extent. Come to find out that the little bit that is rusted is enough to leak water into the rear storage compartments of the 4Runner. How can I fix this? I know I'm going to have to cut into the fenderwell to get the existing rust off but what can I put either on the inside or outside to prevent water from getting into the interior?? Thanks for any input.

 

maybe something like this can help you.

It sounds a little weird, but you can try filling the gaps with that 'Great Stuff' expanding foam in a can. Thats what we did on my truck before it got new quarter panels. Just spray it on (NOT too much!) and you can even sand or carve it once its hardened.

 

just put some new 1/4rs on ... and be done with it .

I've used this stuff before as insulation in some places on a log cabin but never on a truck. Its not a bad idea though for a quick fix until I figure something else out. I might do some fender trimming in the future so I'm not too keen on buying new fenders just to cut them up later on. Thanks for the ideas guys.

 

Try Silica beads or even a regular silicone. Worked for water leak problems in my truck's headlight area.

 

I wouldn't use expanding foam for the fact it deteriorates and can suck up water. If you want a temporary fix that can hold up pretty good, I would use fiberglas cloth and resin.

 

no dont it is open cell foam it will draw water in.
if you do bondo over it as soon as you can it might work. a buddy did this and did not bondo it and it made it rust even worse traped water in the wheel wells
