With the T-9 forming a wax plug very little Chain-L will get past to where you want it. Moreover, the Chain-L will dissolve and mix with the wax making a gummier version of itself.
You could use the Chain-L first, then wipe as dry as possible, and apply the Boeshield on top.
The problem with that is that Boeshield isn't all that effective as a weather barrier when exposed and subject to rain scrubbing action, it's simply not tenacious enough.
This is one of those cases where you have to pick your horse and go with it.
