OOOF... what I thought was going to be a joke thread, actually turned into a real eye-opener! Thanks for that.
I ended up in the hospital once after water-proofing some riding gear indoors. It was a stupid mistake, I thought I had enough ventilation. Woke up in the middle of the night, wishing I was dead from the chest pain while trying to breath through the silicone, which evidently, is bad for you... go figure!
