I've been kicking the idea of do-it-yourself rust blueing around for a while now, and have decided to take the plunge!

My question is: Do most of you that do it regularly, mix your own or use one of the commercially available mixtures? If using a commercially available mixture, which ones do you suggest are the best one(s) to use?

This has probably been asked at some time in the past, but I'm going to broach the topic again.

Thanks,
Cameron
