"We powder coat thicker gauges of steel (10-gauge to \u00BC-inch plate), using a blast operation for some of the heavier parts. We want to test the parts to confirm proper pretreatment coating performance before shipment, but we have some problems with impact and conical mandrel bend testing. The aggressive reaction of the washer chemistry can cause flash rust or other problems on the lightweight panels needed for the bend tests. Is there some way to create a bend test for our heavier materials? How can we confirm that our pretreatment and powder are working correctly?"^^<http://www.w3.org/2001/XMLSchema#string>
