Ranex Rustbuster is crazy brutal on rust - turns the rusted steel black and lightens/powders paint if you get it on there accidentally.
Thankfully my ute came rust free, but I've used this stuff a few times before.
Paint it on very lightly as it will drip if you let excess move about - and it will bubble horridly if it pools for any length of time. If it gets on concrete, it WILL stain powerfully, so do this over dirt or gravel you're not fond of if you can. Putting cardboard or something underneath won't 100% stop it, Ranex eats through... (My driveway and rents are fairly mad at me about the stains...)
I can't wait to have my own fully prepped garage to do the same full refurbishment to a ute.
This stuff sounds potent, just what I need
I'm kinda looking for something I can apply from inside the panel so it seeps into the seams that are starting to rust. I read penetrol seeps into every microscopic crevice but I'm not sure it converts rust. This rust buster sounds like it could do the job but may destroy the paint on the inside as well. I'll have to try both and figure out the best method to do this. I'm thinking of treating the seam rust the best I can with a converting product, then re-painting and sealing the inside of the panel to stop water getting in again followed by copious amounts of cavity wax and fish oil in every cavity I can find. The passenger rear quarter is the worst at this point, I think water got in through the window at the top as that is rusting badly under the rubber. As the water gets in it seeps down inside to the wheel arch getting into the cracked factory seam sealer and rusting it out. I've found similar symptoms in at least 2 of the doors but not nearly as bad.
They also list rocker panels, footboard/door sill panels and so on but all have the same picture.
