So, I don't have any of this lying around. Where would I likely find it?
--Marky
Dive shop, Food prep (the use it on ice cream machines) stores, plumbing dept of some of the home repair stores.
Rmove the o-ring, apply it sparingly, you want a very think coat, best to put a small quanity (think paper match head size) in your fingers and rub all around it. You should see no build up of the silicone anyplace. The treated o-ring should have a "gloss" to it and no build up.
If you get dirt on the o-ring, remove it, wipe it and the mating surfaces on both pieces down with a paper towel, and then reapply.
I am curious, but maybe am just dumb, I just took the back off of my colorado 400t and dont see an actual "o-ring" Where are you suggesting you put the silicone on this unit?
** Nevermind, found it. I was being dumb.
