Do colorants in epoxy weaken it...

Instead of fiberglass, have you considered laminating panels between thin plywood and then using normal construction techniques? Fiberglass can be tricky to work with, especially the part about getting a nice finish, while wood skins can be finished like solid wood. I've laminated several parts for my trailer build using XPS and thin ply, and they're incredibly strong and look exactly like wood. You do have to think about where fasteners will be used, but it's easy to throw in some solid wood blocking when laying up the panels.
These cabinet doors are all XPS+2mm ply + veneer composite:

I would make the same wood framed foam center if I wanted to cover it with glass cloth and resin instead of ply or FRP.

2mm? That's the same size as my FG panels. You built the entire cabinet form this? Or just the doors? How are you holding the sides and bottoms on? Very curious if you found something I did not and improve what I've done!
RJ Howell wrote:Did just that with my 1.0 build for doors and FG'ed over. The wood contracts/expanses but the XPS is inert. That becomes the issue. Live combined with inert. My next step is to try PVC edging with XPS interior. Thinking that may be equally inert? It would have structure to assembled, suability of to hold...
There is an answer out there.. I haven't found yet and still hope to!

No. But epoxy without glass or other appropriate fibers is brittle.

Sounds like time to experiment a little.
Still, I don't expect you really want to store great weight high in the van.
