Re: Phosphoric Acid Rust Neutralizer
picklex is an acid based produst also..
Picklex 20 is used to convert the rust then a primer or rust coating can be applied to protect the surface from the elements.
Rusted metal that is converted using Picklex 20 should NOT be primed using an etch primer. The chemicals in most etch primers are not compatible with Picklex 20. Use epoxy primer if possible.
PPg says NOT to use etch primers over metal treatments..
