blue locktite for stuff you may have to remove, redlocktite for stuff you never want to come loose and you really don't have any intenion of removing ever again.
Don't get carried away and locktite stupid stuff....what do I mean by stupid stuff? Well if you still run points, DO NOT locktite the points cover, espically if you have those philips head screws made out of a slivery substance resembling the softness of butter. Don't locktite your oil pan bolt either.
Personally I make it a rule not to locktite any philips head oem screw on a honda as they are hard to get off as it is without the threadlocker. It is great if you have a stainless allen kit and you want to keep those buggers in place.
and JB weld is not a "stronger" version of locktite
