Thanks Dieseler, I'm at 260k km, I'll Pm you in 100,000 km and let you know how my truck is doing .
(the rate I'm going, that'll take about 10 years)
JJLee The Krown treatment is just a non toxic oil spray that is applied to the underside of the vehicle. They also drill holes in the pillars and parts of the body panels and spray inside them using a wand.
I get it done every November before the snow and salt comes.
This obviously is just for frame and body preservation, it does not repair anything. I'm still looking into places that will do frame welding, for when the little holes that I have get bigger. It's amazing to me how few of the "body shops" around Vancouver can be bothered to do rust work!
