One thing about fast cure epoxy is that you will have more blush, so be sure to consider that.
I'm thinking of making a panel out of some foam and wood frame, with heat lamps attached, that I can suspend from the ceiling. One the layup is done, I'll drop it down and put some plastic sheet around the edges. Maybe.
In case you didn't know, blush is something you need to wash off first. Water and a scrubber.
I'm using Ebond epoxy and I was told that the slow cure stuff will eventually cure fine in cool temperatures, it will just take forever.
I haven't filled it in Oregon yet (mandatory for the attendant to pump your fuel). They let you pump your own fuel on motorcycles and most will let you pump your own fuel if you have a special/rare/really expensive car. So, I think they may let me do my own fuel because it's a PITA for them.
Besides camping, dirtbikes, and overlanding, one of my other hobbies is classic cars. In HS, I drove a 68 Mustang Coupe that I was resto-modding and would travel between Idaho Falls and Port Orchard (where I grew up) so that I could see family. When driving through Oregon, I hated that I wasn't "allowed" to pump my gas. In that car, the fuel would spray back out the fill spout if you tried pumping at too high of pressure. I told the attendant this info and he still insisted that he be the one to pump the fuel. I told him that if he spilled one drop, I wasn't paying for the fuel. After that, I got to pump it every time.
