Por-15 and rust concerns..

[BurnoutZ]

Ok. So I'm preparing to complete some rust removal. I have read some people say por15 bubbles up when applied over rust. Some people on here give me the impression that you apply por15 straight over the top of rust. I bought this stuff, forgot the name, but it supposidly turn rust into black primer... i was planning on using this to destroy the rust... then maybe put por15 over the top of the "black primer" to seal it. Comments?

I have never had it bubble when applying it over a rusted area.

True statement.

POR-15 destroys and stops the spread of rust. Why make more work for yourself, it will be one less step. I would use straight up POR-15 although you can use the prep products that comes with the POR-15 "kit" as well. Some say Rust Bullet works just as well if not better 6 and 1/2 dozen it all depends on who you talk to and what day of the week.

 

If you have lots of scale knock it down with a wire brush. You don't have to sand it smooth because it will stick to any surface prep. If you are installing frame rails coat the inside with POR-15 before welding to the body. Good Luck!
