My main question, is if you put too much foam in and it tries to continue expanding does it actually exert force and potentially alter the panel shape ? ( i presume you could minimise this by providing a number of relief / vent holes )
Or does the foam just become denser if it cant 'move' as it expands ?
For anyone thats done their car with this , any drawbacks or comments on foam filling ?, would you recomend doing it ? ie no reactions with the grp resin etc ?
thanks, nick
Nick, go to your bodyshop supplier and tell them what you are looking for. OE cars have foam in them too. But, not the home depot variety. FUSOR, SEM, and others make foams in various densities, flexible and rigid. Quality bodyshops use them all the time when replacing qtr panels, rockers, etc where there was originally factory foam. I would not use the "great stuff" or anything like that though.
