Rust Prevention and Chassis Protection using POR 15 and Rocker Guard


Nissan made these cars from galvanized sheet metal, although its rare for them to rust it does still happen. I consider rust to be the cancer of the car, so to help prevent any rust forming I used a special POR 15 paint on the frame rails and inside all the wheels wells, as these are the areas that see the most abuse from road conditions. The fenders do have fender liners, but they only cover so much of the fender, and none of the body itself.
Rust Prevention and Chassis Protection
I followed a very specific procedure for this protection, and after a year of use, I can say that it's held up perfectly. So if you're looking for a sure fire way to prevent rust, this is it.

Procedure...
After deciding which parts you want to paint with POR-15, strip away as much as possible from the area you plan to paint. This paint is really extreme, if you get any on a screw and it seeps into the threads, you'll never be able to remove that screw, ever. It's a chemical bonding paint.

Day one: Using soap and water and a brush, scrub and wash everywhere you plan to paint to remove any loose dirt and grime. Then I sprayed Simple Green all over, and using a wire brush wheel attachment on a portable drill  I thoroughly scrubbed the surface, but not so hard as to remove the factory paint or protective finish, just hard enough to remove any remaining grease and dirt. Rinse it all off very thoroughly with the hose and allow it to dry over night.
Day two: When the surface is 100% dry, apply the paint in thin coats, and follow the instruction on the paint can for how frequently to re-apply multiple coats. I did three coats of POR-15 and allowed it to fully cure for a week.

A week later: I applied 2 thick coats of rubberized rocker guard, even though the POR-15 will never chip or flake off, I wanted a rubbery finish to provide a little bit more sound deadening and a nice consistent finish. The pictures below show the finished product:
