You ALL have more room, and better working conditions than I have! I have a very tight, small one car garage, and a old Costco canopy in the backyard that serves as my work area all year round. I put down gravel and plywood for a floor in the canopy to make it more comfortable to work on. I've built two cars from the ground up in the canopy, and it's a challenge, but I get it done.
Just barely enough room to walk around my tiny car! The Austin is 12' long and 4.5' wide, so you can see how tight it is!
Built it and the Falcon in this space. A 10'x20' canopy, including shooting epoxy primer in January! Had to turn the heat off to spray, then back on to dry it!:
