Great document on foam. Interesting section on adhesives. If you could find the US version of the Loctite, it would be worth a test too.

In the video you can see that. It could be there to soak up adhesive and provide a better bond? My concern is just the opposite. The epoxy does not bond well to plastics. Still unclear on glass content as link is down. I would think optimal contact adhesion is when both panel and foam are...

Derek, surfaces should be clean. First I would use a blower then wipe down with damp cloth. Hope those mulch bags are heavy enough, they prohibit viewing contact of the skins. If and when I do this again, I will build a type of press that will evenly provide pressure across the panel. I'm...

I'm still wondering about the VR2. From the video it doesn't look smooth where the epoxy bonds to the foam. Also, not sure of glass content and if that makes a difference. You stated "My FRP seems to have a light fabric on the back so I wonder if that will help adhesion...

I'm really not qualified to speak towards overlaying on the panels. My concern would be flexing and cracking. I would imagine the frp panels would need sufficient glass composition for adhesion. GXV and Earthroamer use the mono shell, but that's a different animal and costs $$$$$$$$. Another...

Page 24 has much of this same discussion and interesting links----- https://www.expeditionportal.com/forum/threads/diy-composite-flatbed-camper-build.184366/page-24

If I do another build, the cabover will become the main bunk for my wife and I. Instead of a point, I would raise it 6-12". The roof would extend out around 2' before sloping to the front. There really is no concern about delamination with the lower psi. When I first started thinking about...

Mine was at 2mm thickness might make the difference. Also glass content. If yours does not adhere, its most likely the VR2. Try buckets of water for weight.

So here is another thought; if the honey comb panels are stronger "and available", why not construct then insulate the interior similar to a van conversion?

Just a few observations; The FRP looked pretty flimsy/bendable compared to what I used. Also noticed the side that is bonded, is not smooth. May or may not be a factor. Lastly, I tried to put as much weight on top of the FRP while drying. Also, be careful to not allow the wood to contact...

I ordered a sample of fiberglass angle and found it to be as heavy if not heavier than aluminum, but that was just one sample. The corners of the box will get the most transfer of energy, it seems to me that the aluminum would fair better in this type of construction. I'd be concerned that wet...

I was hoping for something lighter, but yes, I am satisfied for now. Still think going with lighter guage L channel will make a difference. May also rethink the double layer plywood floor, that thing was HEAVY. I'm pretty sure that I saw in the Everlander's build that they used 1" honeycomb...

If I recall it wasn't that much, call it a skim coat. Good to know about the nano carbon product. No worries, I only used it in the cab over floor and part of the back wall. Everything else got this;

Perhaps a fix for the UV is paint or vinyl wrap down the road. Couple things I notice about my FRP is rigidity/thickness and glass content. Rigidity adds strength and glass content may be a key to the epoxy bonding. Ruff points out that creating deep scratches with a brush may help bonding...

Derek, looking at the description for the Versitex panels, I don't see any mention of UV stability. Also it can be repaired with low heat? I wonder if this is meant for interior more than exterior?

"TerraOps if you want us to discuss somewhere else just let us know :p" Derek, no worries, this is good stuff! Referencing your weight / truck comment; My truck is a 2014 Ram 2500 diesel. GVWR is 10,000 with manufactures tires and rims. I found this interesting that tires and rims were...

Watersmeet; Thank you for your kind words. "So here’s my question, do you know the weight of just the shell you made?And when you say you would build differently next time how much of that is to reduce weight and how much to reduce cost? And if there are other reasons why you’d build...

Cape Lookout. Weather was good for the first day and a half, then the wind kicked in at about 30 to 40 mph. Glad we weren't tent camping. A friend of mine was out there a few weeks back and said it was near impossible to find cover from the wind. Ended up parking next to one of the cabins on...

A nice escape to North Carolina's National Sea Shore
