My 02 F-250 (week end truck) has begun to start showing a lot more surface rust on frame and axles. It's about half rust and half black frame. Are there any products that I can spray or brush on that will convert and stop this. ? Thanks for your help

 

My 2004 is almost 100% factory frame coat, i have spots that it flakes off and all i do is wire wheel it, then use etching primer, followed by dupicolor enamel semi gloss black

 

Hammerite by Rustoleum, sold at Home Depot or Lowes. Can be painted right over non-flaky rust and on steel. Great for frames, and 1/4 the cost of things like POR-15. Hammerite is xyline-based, brush-on, sold in quart cans in various colors, including silver and black.

 

Put on the worst pair of clothes you have
Get a good grinder and slap a wire wheel on it
Get good pair of safety glasses and ear plugs
Get under the truck and go to town, be prepared to get dirty.
Paint with a good quality Semi-gloss paint.
Worked well for me

 

there is a product out there that's not just a paint over, its supposed to stop the rust reaction, cant remember what it is called.

 

used motor oil will cover it up nicely and help prevent more of it easy to put on with a air paint gun.

Ive tried the rust converters by after a while, the stuff peels and the rust is still there.

chain and barb oil works good but its a bear to control the application.

 

Eastwood Rust Converter, or similar.
