I'm planning on doing some rust-proofing to my 1987 110. It's pretty much rust-free but there are a few spots that have a bit of surface rust and that I want to get at with POR-15 before applying some rust-proofing substance (I live in Canada so Waxoyl is not commonly used here, but there are many alternatives in specialized rust-proofing shops).
I am wondering if anything can be done to apply rust-proofing to the inside of the door pillars (which I understand are an aread prone to rust). I thought of having a couple of holes drilled (covered with a plastic plug) on the outside, halfway up the pillar, and having some rust-proofing oil shot in there. Are there simpler or more elegant solutions? Or should I just leave it alone?
Obviously, I'll have oil sprayed inside all the frame holes.
In addition, I'll get rust-proofing blown into the door bottoms (by drilling holes on the sides of the door frames, covering them up with a plastic plug). This drilling, spraying and plugging is a common way to apply rust-proofing to inner body recesses, by rust-proofing shops in Canada.
If I lived in the UK, I'd likely take my 100 to Before-N-After: they seem to do an outstanding job of rust-proofing. I doubt that any shop in Canada could do as good a job on a Land-Rover.
