I bought a 1950's Shasta for $25 last September. Does that count?
Truth be told, I tore it down to the chassis ba'cuz it was all dry-rotted out.
I get "cover sheets" of two-ply Luan from a local hardwood plywood outlet for free. So I'm contemplating skinning my upcoming build with it (probably two layers Gorilla glued over light framing. I like epoxy and fiberglass for wooden boat building and tear drop trailer building, but it's labor intensive, expensive and Bondo won't stick to epoxy (for long). Epoxy only likes hot, dry weather for hardening. Polyester resin delaminates from wood eventually, but not epoxy.
I was thinking about using exterior carpet glue to stick silver tarp material to my cover sheets, wipe it with acetone and brown synthetic steel wool then roll it with exterior acrylic latex house paint.
Whadda ya think?
My goal...
