Need opinions on anti-rust paint (POR15, Rust Bullet, etc)
Hi LXguy. Por 15 is a fantastic product. I am restoring a 69 Swinger and started using it on the floor. A lot of my buddies saw it and started using it now as well. Put it on straight over rust as long as all loose rust is removed. If going over bare metal, the metal MUST be either wire wheeled, sanded blasted or treated with a chemical to etch it. If bare metal is not etched in some way the Por 15 will not adhere to it very well at al. Once the Por 15 is cured it will not peel. You can hit it with a hammer and it won't flake off. It is very tough. Great for around windows or on places where scratcing may take place such as putting on trim. The product cures by moisture so the wetter the product gets the harder it gets. The product directions say to topcoat it anywhere UV sunlight gets at it so no good in the sun on its own, as it has to be topcoated. Also best way to top coat is just before product is dry, top coat with a good etch primer so it takes a good hold on thr Por 15. Don't try to sand it after dry and apply primer or you will curse trying to sand this stuff. It is too damn hard. I have heard none of my buddies say anything negative against the product.
