We have all tried welding a rust hole, only to find that we had made the hole larger, and the problem bigger.
By spraying pure metal onto the surface, filling in rust holes while also galvanizing the area, the problem is solved. The metal bonds mechanically at approximately 40,000 lbs. PSI, and can be applied as fine as .001 thousands of an inch to 1 foot thick.
Rust holes of any size can be fixed, yet the process is slow enough that the surface temperature only reaches 100° F. which avoids warping.
At Rustbusters, we do repairs on anything made of steel. We also design systems for your commercial application.
