I had the same thing happen to a Boss CH-1 Super Chorus that I bought from a guy on eBay. Actually, I think that's why he sold it on eBay and he scammed me...but I digress...Anyway, I tried the same type of insulation that you're talking about and it only worked for a short time and quickly failed. I hope your fix-it works. Mine didn't and I had to toss that Boss pedal in a dumpster.
The mod that the OP is talking about by Steve McKinley
only seems to be around $50. He may be willing to repair your pedal.
I may send my Boss LMB-3 to him for the Thunder mod too. I usually buy my pedals used from eBay so I don't have much $ soaked into the pedal yet anyway.
