Well took the Procedure, None of us knew anything about DCDP as well as the test lab. Their machine keep turning off DC mode and had to take the procedure back at our shop. Keep telling them the gas was wrong and it was balloon grade and they keep telling me it was high grade. I took the vert. and horn. with this balloon grade and ran out before the over head. New gas was high grade and pass the over head test. Because of the bad gas the test lab let me retake the vert. and horn. again,if I could get them back to them by 9am the next day. What a night mare, the gas can make you or break you, thanks for the help Jody !
