Has anyone used this http://www.blastercorporation.com/Corrosion_Stop.html
I have used some of their products in the past and really like them. I saw this at the store the other day and decided to get it (was only $5). Sprayed some on was quick messy, thankfully I wore gloves.
Was just curious if this stuff actually works, kind of tight on money and didn't want to plunge into a couple hundred for an undercoating.
