The only thing I didn't like about it was when you accidentally got some on the lips from your fingers,,,, a horrible sort of sweet taste.
I actually don't mind the taste
Loctite 222 is what Barrett recommend for their rings, not easy to find over the counter but plenty available on eBay.
Torque wrenches can generally be bought from bicycle shops, look for packs of MAMIL's lingering out front. Resist the urge to check their packages or moose knuckles and head inside to the tool section or failing access to a good bike shop, there's always eBay
I have one of these because I was specifically after in/lbs though this tool can be switched between various units http://www.ebay.com.au/itm/1-4-1-25-25Nm-Bicycle-Bike-Digital-Torque-Wrench-Repair-Tool-/161458952332?hash=item2597b4188c
