The Paragon is just a really nice well built mask that has worked well for me, never a leak so long as I made sure it was under the hood.
JBS, Johnson’s baby shampoo (~20 to 1)
New mask, did not use flame or toothpaste on it in the long long long thread on mask treatment a run in the dishwasher showed great promise, if that doesn’t work I’ll flame it, if that doesn’t work toothpaste and last option is remove the lenses and do 48hours in ammonia.
It looks like it will be a good choice, if you can get a price break all the better, I didn’t want to be indebted to anyone over it.
