what happened to the fuel preferance topic any way...
Corroseal is widely know in the marine industry, I happen to work in it, and have used alot of it. You thought a car on a salted road is bad, try a steel boat in salt water 24/7... The stuff is magic, I couldn't imagine life without it. You can use it to stop and prime any rust. Lot's of rust, or little rust. You just chip off loose rust flakes if it's that bad, dab on some milk like liquid, and it converts the rust. If you're doing little spots like the edge of your door, and get it on your paint, you can go back later with a damp rag and rub off the stuff that didn't touch rust, no damage to the paint. Nice for detail work. But here is the description from their site (corroseal.com):
Corroseal™ eliminates the need to sandblast rust by converting rust on steel from iron oxide, rust,to magnetite, Fe304, a black, inert substance. At the same time, it primes the metal for a final paint coat. The unique patented rust converter formula in Corroseal™ will convert heavy rust in one coat. Very heavy rust, 1/8" thick or more will require two coats. Corroseal™ is the best way to deal with rust because it is less expensive, takes less time, and is much more environmentaly friendly than sandblasting. It is used on ships, oil storage tanks, buildings, motor vehicles, trailers, tools, wrought iron furniture, etc. Wherever you see rust, you can use Corroseal™. It serves as the primer and bonds with oil based paint, epoxy, urethane and most other top coats. Corroseal™ is non flammable, non toxic, non corrosive, and biodegradable.

You can get it on their site in 1 gallon jugs being the smallest. But, I'll probably have some sample bottles (4 oz), in a few weeks. which is enough to last a while. If you want one, let me know. My car barely has any rust, so I dont really need them. (oh rats)
