Chuck,
As per an article I found on the 'net, I used the Pilkington's, diluted to about 50% strength after the first coating at full strength. I am only aware of two commercially available rust blue solutions...the Brownell's house brand and the Pilkington's. I've tried them both on fluid steel tubes and had better luck with the Pilkington's. If anyone knows of a better commercially available rust blue solution, I'd appreciate hearing about it.
