Many years ago I cut my teeth building infrared systems that hung under the=
 wings of fighter jets.  High g maneuvers, slamming onto flight decks and t=
emp extremes were the norm for operation.  Our testing included mechanical =
shock/vibration, and thermal chambers the size of one car garages.  Pretty =
intense.  We used blue, red, and green, per the specifications.  It seems l=
ike there was a purple as well, but it has been too long to be sure.  Anywa=
y, we always used the Locktite primer, as in every time.  Oh, and we referr=
ed to green Locktite as 'liquid weld', because it had to be heated signific=
antly for even a prayer at getting it to let loose.  For automotive usage I=
 don't have the primer, but, I use acetone after cleaning everything up rea=
l well with wire brushes etc.  I think a clean surface is pretty important =
for the formulation to work as designed, at least it was for applications w=
here a loose piece of hardware could have stopped a very important show.

Oh, and the stuff that went onto tanks.  Wow.  Now there is a filthy, rattl=
ing, big BANG environment where you didn't want anything rattling loose eit=
her.  Locktite rocks.

Just my .02
