My truck (99 Expy) is very clean but the bottom of the doors have some rust going on. I know the best way it to replace them but living in the snow belt, it is impossible to find good used doors plus I really don't want to spend the money to do this. I had a body shop look at them and say they could clean them up for $500.00 but couldn't guarantee anything. At the same rate, I would like to stop the rust as much as possible as the truck is clean and runs good. I saw an ad on here for stuff called Rust Bullet that seemed promising. Has anyone used this? Is it any good or is it snake oil?

 

For rusty motorcycle tanks ( inside ) a lot of guys use POR-15 to paint the inside of the tank.

Just a thought, has good results with the inside rust gas tanks on bikes, so if it works sitting in gas, I would imagine it would do OK on the bottom of the door for a stop gap. I have also had this problem in the rust belt here, always trying something to stop it. That seam is a place that rust loves to live and breed in.

I have used POR-15 for quite some time and it works incredibly well. Please note that the POR-15 clear will yellow over time, unless you use the Glisten... which I don't think would be applicable to your situation.

Be sure to wear gloves and work in a very ventilated area.... Please note that if you get this stuff on you.... you'll have to wait until you shed that layer of skin.... it works that well. Also, wear clothes you don't care much about and wear long sleeves.

Also note.... do not try to clean up the rusted area..... just knock off the loose rusted metal and paint straight over it. It's actually beneficial to give the POR-15 something to adhere to.... It'll seal it up tight so rust cannot continue.

I think that about covers it. Good luck. ;-)

 

How much POR 15 would I need for frame and suspension? I've read that a little goes a long way. 2 quarts enough? Any special brushes or clean up supplies needed? Thank you.

 

jump n,

I've never done a complete frame and suspension job, but I would think it would take at least 2 quarts. I would start with the 2, since POR-15 isn't necessarily inexpensive. To apply, just use a Foam Brush, it works great. Once again, it'll run on you, so make sure you have drop cloths and careful when you wipe the sweat off of your forehead... you may just be wiping this stuff on you..... (Something I've experienced first hand).
