Read the web page. Don't you get frightened when they say just to paint over that rust?Sends chills down my spine. Could be a good product but that turns me off.

POR15 has been around for a very long time...it works exactly as they say it does. It's been used on many rusted out vehicle restores with great success. I don't think I'd undercoat my truck with it, but that's personal preference.

I've used Rus-Fre since 1985. The BB gun they sell is cheap and the under coating holds up well. They sell all the stuff you'd need for short change. You just need a compressor. I laid a large sheet of plastic under the truck to catch drippings and a good bug and tar remover in case you got some on the paint. Paint thinner will work too.
The pictures shown in the posts above look like Rus-Fre. Napa sells it as well as lot's of places online.
