Thought I had some 700-1 left. I don't. What's the best substitute that I can get on a Saturday at the parts store? Or should I just wait? I really, really need to start painting tomorrow.....

My understanding that you take care of the really nasty stuff first with 710, and 700 catches what the 710 missed. You can see the difference on your rag. After 1 or 2 times over with 710, and your rag looks clean, then try a different clean rag and 700. A lot of times you will get more dirt.
Prepping the Surface: Metal or aluminum must be clean of all rust, oils, and any films. Never clean metal with lacquer thinner, acetone, or reducers of any kind. When prepping aluminum and metals for epoxy always sand aluminum or metals with 80 grit DA paper. Clean bare metals or aluminum with SPI 700 Waterborne WGR, clean with 710 WGR then let it sit 30-60 minutes before applying SPI Epoxy!
