Adhesive for attaching Filon to roof
Howdy all. I have been working over the past few months on repairing my pop up truck camper after the roof had an RUD (Rapid Unscheduled Dissassembly). I've been reading up on all my options for get...

When I built my small camper/large canopy, I glued the filon to a luan roof deck that covered the foam insulation with Weldwood contact cement from Home Depot. That was in 2006 and there is one or two bubbles up there now where the glue has failed....I suspect due to heat (heat softens contact cement).
I have found it very difficult to glue to open cell foams because the glue dissolves the foam. The one exception has been a black closed cell foam that I used to use for whitewater canoe outfitting. I have successfully glued this foam with (Weldwood) contact cement many times. The joints are solid to the point where the foam fails before the joints do. It takes two coats on the foam though because the first coat soaks in somewhat. That foam is very expensive though.
However you do manage to bond your filon down, be careful of compound bends when you lay it out. I really struggled with the bend over the front cap when transitioning from the slightly arched roof. I wound up just putting a seam at that transition, but perhaps someone else has a better suggestion.
I hope this has helped some.
