Rusteco Gel

Rust on Steel with Powder Coating

Rust on Brake Backing Plate

The brake backing plate from the GreaseMaster section has popped back up, this time for rust removal, of course. This was the first thing I ever tried with the Rusteco Gel and it took some time for me to figure out how to make it work effectively. Click image to enlarge.

As you can see, the rust is gone from the backing plate and the powder coating is still in great shape. Through several trial-and-error applications, I figured out how the Gel worked and how to make it do what I was looking for. I think a pressure washer would be ideal in this application, but I don't have one. Instead, I used a rag and a brush to remove the hardened Gel as well as ultra fine steel wool (0000) for more aggressive rust removal in areas where it wouldn't damage the powder coating. Once dried, the Gel becomes hard, very much like an epoxy, but unlike an epoxy, it will come off with water and agitation. This definitely wasn't the ideal test to show the most effective way to use the Gel (as I utilized several application and removal methods during this test), but it does show how well it works on steel and that it doesn't harm powder coating in the process.

Close up, you can see how effectively it managed to penetrate the rust and remove it as well as leave the powder coating completely alone. I simply used a toothbrush and water to remove the Gel, however, it is far more effective (meaning fewer applications) if used with a hard bristled brush, scouring pad such as a paint stripping pad or steel wool.
