Stopping rust in hard to get to places?
 

i just cut out my inner rocker and cab corner and i want to put something on the insides of the cab supports to prevent rust. what is best and also what is best to paint my floor pans with in the cab and under. also if you dont mind telling me what steps you did from bare metal to done. and what kind of seam sealer works the best for unseen seams and whats the best for the roof around the drip rails.

Good question; should be cool to see what everyone suggests. I've heard a lot of good things about POR-15 and I know it's thin enough to get into the tightest of places. UV breaks it down and makes it caulky though. It should be fine in places that won't see sunlight; in other places it'll need to be painted over to keep it from starting to look bad and breakdown.

Over here in the UK we know a bit about rust and how to stop it. In cavities I use an anti-rust wax called Dynax 50, comes in a big aerosol (rattle can) with a long prope with a 360 degree spray head, you find a convenient access hole or drill one if neccesary and insert the probe and give it a good dousing in wax, it creeps into panel joints and is self repairing so if it gets scratched it heals itself. It'll happily go over paint or bare metal and will keep the tinworms at bay for years. There are a fair few different brands of cavity wax available. Waxoyl is the biggest, Dinitrol, Dynax are others. When I replaced the rocker and inner it got a good spray afterwards.

Here's a link to a previous discussion with some good info on it. Panel wax discussion begins about post #6

Cab Corner, rocker panel seam?

That dynax s50 looks great. Can't find it here in the US though.

i thought about using Eastwood rust encapsulator on the floor boards, hard to get places while their open and, underneath the cab, the spray visible areas with Eastwood extreme chassis black, using the encapsulator as a primer.

cylinder fogging oil works great, just reoil every 3-4 yrs.
