How to Stop Rust
Q. We make automated pay stations for parking lots, the machines that allow the customer to pay at the exit with a credit card or cash. We have had some problems with rust breaking out of the seams at the base and around the door panels that provide access to the interior of the machine.

Q. We have a large part made out of tubing that is welded together. The tubing has a lot of oil seeping out of the welds when the part is heated and causes a defect in the cured film.
