[bret]

Back when I was working in a totally unheated garage and had no money, but a lot of time...I made my own version of "radiant floor heat".

[1] large piece of cardboard [like a refrigerator box]
[1] electric blanket from Wal Mart
[1] additional large piece of cardboard

I slid this under my car [a blown injected Fairmont at the time] to lay one as I worked on suspension, brake lines, exhaust, etc. I would slide it over to the workbench if I needed it there. It was cheap, easy to move, very effective and disposable if you ruined it somehow.

Now every building I own is radiant floor heated. It is truly the only way to go.
