Thread: Anybody used Rust Bullet?

I was looking at Rust Bullet on their web site and am thinking about drilling holes in my rockers to spray this inside. I would use rubber plugs to fill the holes so it could be redone if needed. Plugs wouldn't be visible except from underneath the car. I need to do something to help save my rockers before the cancer starts to make holes.

My experience with these types of products is that they actually cause rusting by plugging up the drain holes and the water sits in the fenders or doors and rots. The holes drilled are often the first thing to start rusting. There is no better protection than good paint. Maybe I just saw a lot of bad installers work. IMO

I know I have rust in my rockers right now and want to slow it down or stop it. Paint won't do anything to neutralize the rust. As much as I love my GP, it is my DD so I don't want to spend a fortune to fix rust that isn't making holes yet. Maybe I'll just make a few small holes and spray it all down with penetrating grease every year.
