Jack,

I have never used it. I do use oxysolv from Eastwood, it is just phosporic acid, I spray it with a junk mini spray gun or you can brush it on, should clean afterwards with lacquer thinner.

A light sandblasting is best on rusted steel or a wire cup wheel on a body grinder for floor pans.

Zero rust is just the best high solids alkyd enamel value you will find on the market, rust-oluem is just cheap thin junk.

In a perfect world you will have clean steel with an epoxy primer and a modern urethane topcoat. For a chassis or undercarraige, floorpans, etc. degrease and clean, apply a few coats of black zero rust and you are good to go. I had a few small rust spots resurface years later, just clean and touch it up. Now, if you use toxic Poor-15(expensive and hazardous to your health) and it flakes off years later you have a big problem and you cant just touch it up.

I turned Jeff Maltby on to ZR, he used the POR product on his 49 and it failed years later.

He is a happy camper, give it a try.

 I live on a 50 yr old steel yacht in the Caribbean. Im always chasing rust! I use phosphoric acid, currently a product called phospherizer from Forto chemical co. If you go to any good paint store or weld shop, you can find phosphoric acid in gallon jugs for about $13 per gal. Depending on the amount of rust, you can dilute 5 to 1 and sprey it on with a plant spreyer or soak the part in the acid. After its clean, rinse, dry and prime. If you let it dry with the solution still on it, itll get a white film which needs to be wire brushed off.
 Hope this helps.
