Rust Conversion and Rust Stop Paints
I've use POR-15 for about 5 years. Great stuff. You can achieve a great high
gloss finish with POR-15 more easily than almost any paint I have tried. I have used it on heavily rusted frame members as well as prepainted surfaces. The only (optional) pre-painting chemical is another POR-15 product called Marine Clean. (A very caustic, aggressive water based solvent that removes oily film which POR-15 doesn't like.) Spray it on, hose it off. As I read the instructions the only time a primer is recommended is when you have new metal. I have primed some surfaces before I used POR-15. I didn't like it. The Rustolem primer I used was much softer, when dried, than the POR-15. I didn't like having a softer underlayer for the POR-15. It can be applied directly to heavily rusted (descaled) iron and seems to me to work very well, because of the extra tooth the rusted surface provides. POR-15 is one part, moisture curing, polyurethane paint. Incredibly tough. You can almost not abrade it with sand paper. You can just abrade it with a file and a strong arm. Striking the finish with a hammer doesn't do much unless you deform the metal underneath. At least 2 coats are recommended with about 3-4 hours between coats. In desert climates almost 8 to 24 hours can be required between coats (it's moisture cured.) Cleanup is a bit of a bear. Lacquer thinner works. If you buy POR-15 I would strongly suggest small containers. Ebay is where I bought my supplies although many automotive paint stores also carry it (usually in quart cans). I recently use POR 2500 degree high temperature paint on my new muffler system. I'll tell you how it works in 5 years. Happy trails, Eric Perplies 96 PT-42 In WA loading up to follow the sun. |
