Hi guys and gals, I'm rebuilding the roof on my 91 Coleman Newport due to extensive water damage. I've got it down to the bare aluminum skin and am going to build a wood "frame" and fill with foam and skin with luan but I'm wondering what's the best adhesive to attach the wood to the skin with? I'd just use WEST system epoxy but that'd be a LOT of epoxy, hundreds of dollars at least, so I'm hoping there's something I can purchase in a tube from Home Depot or the like that I can squirt with a caulk gun to do the job that won't cost as much. Anyone got any recommendations? A tube or gallon that can be spread that'll do the job would be great. Thanks!!
