1"X2" HRS tubing.Our powdercoat equipment is Kcoating for which imported from Swiss.We powdercoated the parts and found there are dead spots,between tubing and CRS.It looks like have a dotted lines on the corner.
manufacturer - Xiamen,China
David you do not state that you clean the weld joint... maybe this is the cause of the defect. Try linishing the joint prior to PC.
