Re: Phosphoric Acid Rust Neutralizer
I did a frame off a a 68' P/u about 15 years ago and I used ospho on everything that had rust. I sanded everything down to bare metal sprayed with ospho, let it dry and then I sanded it back off. Sealed with a PPg etching primer, then a k-36 primer and then PPG paint and clear. Truck still lokks good today.
