Powder Coating Clinic: Oil Seeping out of Large Welded Tubing
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. We cannot get the oil out of the tubing in our washer. We tried cleaning up the defect and running it again, but oil still runs out. How can we get that oil out of the tubing?
