As its name suggests, Tri-Flow is a mix of ingredients, and I think it's something like a paraffin wax, a petroleum based oil, and PTFE, with solvents to make it all liquid. Some mechanics might not like its tendency, from the oil, to pick up all the stuff that makes it turn black, but it works to lubricate and protect metal from oxidation. I've used the Rock'n'Roll blue, and I think it's more of a wax/PTFE suspension in a solvent, maybe with some binders and other secret stuff to help it stay on longer. It strips the old stuff off as you apply it and wipe the chain, and stays cleaner than Tri-Flow and other oil based lubricants. The exact compositions are trade secrets; someone else might have better insights into what their components are. Either one is much better than nothing, but I've had good experience with Rock'n'Roll too.
