Loctite is expensive, but that is a lot of money. However, a 250 ml bottle is way more than you will need, and there is little sense in buying quantity for future use as the stuff has a shelf life. Like all CA products the shelf life can be extended if it is stored in the fridge. However, for best performance one should use fresh product whenever possible. Look for a 50 ml bottle which should be readily available. Amazon has the 50 ml bottle, which is far more than enough, for $45 US.
