So I was reading the archive + found a thread on foam stiffening. Icemark did it to all(?) his cars + used ITW autofoam. But the problem is, ITW doesn't make it anymore. Or at least they don't call it autofoam anymore.


So what do people use to stiffen up the chasis? I know it needs to be around 5/10 lbs? in density + needs to be a proper 2 part epoxy that you mix + pour into the chasis, then tape over it.
