Killing Rust on Cars & Trucks for Winter

Killing Rust on Cars & Trucks for Winter. Chassis Saver or POR-15 is great for treating rusty metal of a metal surface that is sandblasted or rough. If the metal is smooth or you have a combination of rust and painted surfaces you want to use a special high-zinc rust-killing primer for rusty primer. The main problem with Chassis Saver or POR-15 is being applied to a smooth surface because it could peel. That when you want to use a good zinc primer designed for going right over rust. Most of the time, the bottom of the car is see rust starting in small areas. I don't use any fancy expensive cleaner to prepare the surface for primer. I like using a product that has been around for many decades for cleaning whitewall tires, since it is safe for paint and rubber and will break down dirt fast. Also plain dish detergent will get off the deep grease and dirt. A cheap pressure washer will get all the hard to reach places and clean out seams where you want the pain to stick and fill in to prevent any future rust. Then I use a spray truck bed liner from the same company. The spray cans of truck bed liner are more expensive than brush on but the spray gets in those places where water, dirt and salt accumulates and rust starts. That's a very important consideration. A leave blower or air compressor will speed up drying times. Also if you are doing this in the winter in a garage, shed or enclosed car port, a forced-air space heater will work well so you can paint and also dry the paint fast. Truck bed liner will go over a quality rust-killing zinc based primer and the truck bed liner is impervious to water and very strong against rocks that hit the underside of the car, truck or jeep. No paint is as strong as truck bed liner.
