question about foam coreing

[truckwrench1]

would foam be strong enough as a core to build some seat frames (non performance ) out of and then if it is what weight glass would work best for this. revamping familys pontoon and looking to do something a little different oh and it only would have to hold a 250 lbs fat man lol !!!

Hey guy are you talking about using a two part foam or foam core ?

[truckwrench1]

i was talking about core or foam sheets 4 by 8 sheets instead if plywood hoping to make them lighter but still hold the weight of adults is this possible and would that require vinyle ester resin

Hey guy have you given any thought about using Coosa ....... http://coosacomposites.com/bluewater.html great stuff and will never rot and can be used with your resin of choice ........Poly , Vinyl . or Epoxy.
