    Both are rust-treating paints. You probably won't be able to find either local, but they are easily available on the net. You typically buy both by the gallon. Both can be applied using either a spray gun or by rolling/brushing them on..

    would you know the prices on it? how many gallons would i need for most of the frame? any special prep work involved?

    also I know rustoleum and duplicolor both make and undercoating spray paint that are both very high quality. may help you save time and money and still give you that quality look.

    ive heard some bad stories about undercoating with the frame continuing to rust underneath of the paint after its all finished, but i dont know if thats true or not

    Its about 50 bucks a quart but if you're only doing the frame rails you probably wouldn't even use one quart to do them both. I did the complete underside of a camaro and the entire gas tank with just a little over one quart. You do need to scrape it down to bare metal (or bare rust) first and then use their metal prep product along with rinsing it in between steps.
