Use lock-tite a fair amount myself... I'd use it in a heart beat!
There are three colors that I know of:
Blue- light/medium weight use. It can be easily removed. (Great for grips and frequently removed screws)
Green- Can be applied to screws in place. (hard to find)
Red- Considered to be for heavy use. Takes a fair amount of heat to remove... (I use this for screws I don't normally remove)
