I have media blasted some steel tubes (about 8 inches long and one to two inches in diameter). The outside of the tubes is no problem, but on the inside, I’m down to bare metal in some places and a tiny amount of rust, mostly in the bottom of some of the tiny pits where the rust was.
Do I use Rust Converter and then Rust Encapsulator? I ask because the Rust Converter FAQ says it isn’t for use on bare metal and needs some rust to work. I also read that the best process is Rust Converter followed by Rust Encapsulator. I have both products in aerosol cans. What should I do?
I’m still doing prep work and repair on a vintage motorcycle and won’t be painting for a few months at least. I’m leaning toward acrylic lacquer paint because I’m a woose about the respirators, air supplies, etc. for urethane, but in case I talk myself into urethane paint, I’m glad the Rust Converter and Encapsulator leave that door open.
Based on what you are describing with the interior of a tubing, I would recommend you using our Internal frame coating. This product will lock down the rust inside the tubing and protect it in the future. This way you do not have to worry about getting converter on areas that do not have rust.
