Shortening curing time

Tip: I really like the February Tip of the Month on filling tires with silicone caulk.

Colin stated that the caulk cures really slowly because air cannot reach the RTV. Actually, RTV cures in the presence of moisture rather than air.  An old trick used in the moldmaking and automotive worlds is to douse the RTV with water to speed up curing.  

I think this would cure much faster if the inside of the tire is drenched in water just prior to placing the rims and filling. I haven’t tried his approach with tires yet, but I have used the water approach with RTV, and just a few drops drastically shortens the curing time.

Even better if you could mix a little water with the RTV and then inject it using an epoxy-style syringe.  
I hope this suggestion helps.
