buddy of mine had it installed on his brand new F150 2 years ago, the fender started rusting where the contact was attached this year, so I'd have to say they are JUNK!

good luck!

I have one on my Saturn but it came with the car.....underneath is somewhat rusty but rest of the car is fine....I wonder why?

As mentioned above, they DO NOT work.

My mom has one on her 2000 Expedition. And while the body has no rust, the factory reese hitch got pretty rusty, and we had rust streaks coming out the drains in the bottom of the doors.

It now gets Krown. The streaks are gone, it now gets "Krown trails" instead ;)

I have heard that they are junk, and I personally go to Krown to get the rust proofing done on my 90 stang, which is still rust free.

1989 Town Car. 337,000Km on it now.

It used to be sprayed with Rust Check, now gets Krown. You can see it seeping out all over the place. 20 years of rust proofing will do that I guess ;)

I haven't seen any of the rust proofing seeping out of any where on the car, the only thing is that it drips the extra off over the next couple of days after it is sprayed.

It takes a number of years ;) The above car has 20 years worth remember.....
