Painted the floor with some Rust-Oleum high gloss protecto paint. I bought a quart of it and just brushed it on with a disposable brush, I figure it's going to be mostly covered up eventually anyway. Didn't want to buy a new transmission cover so I fiberglassed the rust holes in it, I know that's cheating but I'm on a budget, well actually my budget is blown. Got a gauge installed, it's actually starting to look like a truck now.
