I have a Blazer that doesn't have any undercoating and it is starting to look pretty bad, especially the frame? I was wondering if there is a good rust inhibitor that I can spray on the frame and springs and then coat it with a good undercarriage spray?

Thanks,

This sound like what you're looking for?

Thanks for the info Fritz!!! I'm going to order their little test pack to check it out. I might do a before/after photo and post on here ;)
