oh yeah...paint. heh. my bad.
The interior of my car doesn't sit in water dude....
intresting stuff
I dont know much about expanding foam but (funkdoc.) when you say it sets exothermically i understand how it works, fibreglass cures exactly the same way.. so its a 2 part process? ( as in, you use some kind of catalyst?)
The only problem i could see with it would be if you use a fair amount of it, wouldnt it crack? I dont mean after its cured, but with fibreglass, and the exothermic effect, if it heats up too much (if its a large amount) it cracks.. cracks, smokes and will burn the shit out of you if you try to touch it when its at that stage...
And if the foam has heaps of little bubbles in it which could soak up water, could you use some kind of silicone to seal the edges of it?
hey got a pic about filling expading foam into chasis..
I was thinking to do this and remove the sound deadening to my car, so that I can keep the weight down and chasis become stiffer plus I can still listen music as these things good for block the noise out inside the car. I was interested in doing this to my car but if it collects water and cause my car rust then that's no point doing so.
The stuff that comes in a can will collect water and doesent dry that stiff either. You need to buy the proper marine grade shit that comes in two parts and dries rock solid and waterproof. I can't remeber what the stuffs called but have a look around on club4ag in the tech section. I think it has a write up on whats involved.
