I'm not sure, but when I got there they were testing a number of other blends. They prep and coated tanks, then cut them apart to see how well it bonded and coated.They have a tumbler set up and do large batches of tanks. It's quite professional, and not just a can of caswell sprayed in a tank.
They weren't just using a can of caswell. They actualy test new coatings and blends as they go. When I was there they were just cutting a tank apart they had coated for testing. Call them up ans check with them, they aren't just a paint shop doing this on the side, they do a significant business just on their tank treatments.
I just messaged T Markus customs to learn more about their tank coating. Also, I was searching for metal tanks when I came across this thread with lots of information
