So the truck I just got is 99% rust free. I will fix that 1% and want to make sure I don't get any rust coming back especially in the problem areas. With the help of the POR-15 products, I want to be proactive to treat common rust areas before it comes. I was poking around the truck on the weekend and have some questions/observations:
Rockers and cab corners:
Would it be beneficial to cut openings into the inner rocker panel so I can coat the inside of the rocker with POR-15? The sealing off of that area obviously doesn't work anyway as we know it's a common rot spot. My brother had the idea of drilling a couple holes in the sill and filling the whole thing with polyester resin.
Cab corners seem to be open at the back so cleaning them an coating with POR-15 should be easy enough.
Rear fenders:
I thought these were single-skin but as I was feeling around it appears they are inner-skinned and I would imagine where the seams are is where the moisture collects and rust. Would it be a good idea to seal these seams up? How can I get something in between the skins to prevent future rust?
Windshield and rear window edges:
I fear getting rot here as that would be nothing but labor to fix it and would be big money. Any way to access the bottom of the windshield on the inside to get some POR in there? The rear window shouldn't be too bad I would think.
This truck is my weekend toy so driving in the rain will be as minimal as possible and we get little snow here in the winter so the roads aren't salted too much either. Even as such, I want to do something about it now while the metal is still good rather than just wait. Thanks.
