POR-15 vs Rust Bullet vs Zero Rust, etc
 

I gather POR-15 has been around for awhile...what's anyone experienced with the others? Any recomendations?

I have used Zero Rust for several years. It is a great rust sealer and protector, inexpensive too. Here is a link...

Zero-Rust: Can it just be sprayed/brushed onto surface rust areas afetr wire brushing etc? What about the benefits of applying it to more severly rusted areas?

I recomend treating rust with Ospho or Jasco before POR 15 or brand X. It comes in a one quart plastic clear bottle available at Home Despot for $5. it is phosferic acid. converts teh iron oxide into iron phosfate, a less oxigen hungry substance.

What he said. Acid and wire brush and more acid. Also, I sandblast what I can. Rust is like Schwartzennegger, "I'll be back."
