Apparently successful wart treatment

A year ago I mentioned having a wart that survived many rounds of prescription-strength acid and cryotherapy. I suspected that the local healthcare providers were simply not being aggressive enough and it now seems that I may have finally dealt with it successfully myself. Back in January I sprayed it with half a can of some aerosol for quickly cooling dental impression material and that seems to have been sufficiently potent, I still see no wart returning. What others should do is not mine to suggest but I am glad that my impatience led me to try this off-label approach.
