Ok my brothers!!! I forgot when, Big Al and I was going back and forth a while back with PMs about Duragloss. I'm surprised he didn't block me!! HeeHee.. Anyhoo, he wrote in one of the PMs how to mix DG #951 and #921 but I forgot the ratios. So I mix it 50/50. It realy did work great. Maybe he will chime in and give us the ratios. So the number I come with is 951+921. Get it.... I thought it worked great....
