The Stovebolt Site Forums The Shop Area Paint and Body Shop Giving it a try

We have a 1949 Studebaker pickup with very bad surface pitting that we would normally blast to the bottom of the pits using our wet blaster to prevent warping. This takes a long time when every square inch of the surface is pitted so we are trying KBS rust converter applied with a brush and not reduced. Hopefully this will fill the pits and leave a flat surface after wet sanding. Prefer KBS over POR15 as it seems to give better top coat adhesion. Will leave to cure for at least a week in hot Texas sun. We use the white with color tint to give the approximate hue of the finish top coat. Will follow up with a thumbs up or down.

Interesting. I'm looking for a system for my chassis. It looks like a moisture cured urethane much like POR-15. The supplier up here wants $200+ for a gallon of POR15 (without their prep components), which is pretty hard to stomach. KBS has a kit with a gallon of the rust converter WITH prep for less than $200. Unfortunately, I checked their website and it's not as readily available as POR15, and they don't even have a supplier up here (no surprise there). And they don't even mention shipping to Alaska. I'm sure they'd either balk at shipping to me at all or want to charge 3x the product cost. I'm likely shut down for the winter on any kind of coating anyway. We got our first snow overnight, and my frame is still sitting out in the driveway.
I'll be interested to see how your project turns out.
