POR-15 Application

Q: POR-15 Application

Can anyone tell me more about POR-15? Is it black, clear? Can it be painted over?

A: I used POR-15 on the undercarriage, firewall and frame of my car. It is not as simple as they make it sound to use but is worth it. You must thoroughly clean the surface. Do not use any petroleum based solvent (laquor thinner) because the POR 15 wont stick. The surface must be completely oil free but can have solid rust. Use a metal etcher on all bare metal and scuff any remaining paint. You can brush or spray the finish. If you spray tape off everything within 10 feet because over spray will stick forever!! I have heard that it is difficult to get brush marks to flow on highly visible surfaces. You must recoat in about 4 hours or when the finish is dry but tacky. I did find some problems.

1. You can not remove POR 15 once it is dry

2. You must recoat when it is ready-not when you are.

3. It burns when it gets in your eyes.

4. I had a problem with the gloss consistency when the finish dried. I have heard that is a typic

Hope that this helps
