Don't use grease, use the appropriate version of 'Never Seize'

i was wondering if you guys put grease on the (new) bolt(s) when you
reassemble it so that it can't happen again.
when i reassemble stuff with steel bolts into aluminum castings i put grease
on the bolts but i'm wondering if that's a bad thing to do. so far as i
know the bolts that i've done this to haven't worked themselves loose, i
torque them down to the specified values, etc. i always figured it was
water getting in there that caused the problem to begin with, either that
the water caused the aluminum to corrode and locked the bolt (with that
white aluminum corrosion frazz) or there was a galvanic reaction between the
steel and aluminum that corroded the aluminum and created that white frazz
that locked the bolt.(?)

b.w.

WHen that happens to me, I drill the broken bolt with 1/2 the dia of the
bolt. By all means go slow and true! Tap in a flathead screwdriver bit
that fits to a 3/8 ratchet, tap it in tight. Apply small heat to the AL ,
hope to hell it turns out, 9 X out of 10 this works for me.
