I don't know how much the beam polishing added to the mix, but again it was something I could do myself and it only cost my time and a minimal amount of materials. You can polish about 95 percent of the beam after new rod bolts are installed if you are careful to stay away from the new bolts. I have a couple of kits in stock but I never know when I will sell them. I might not sell any for a month and then suddenly may sell 2 in 2 days. Depending on my schedule, I can uually make kits up within 3 to 4 days.
