Is it "OK" to use SS on an aluminum tower?  HA!  I say it is MANDATORY!

Way back when (late '60s or early 70's) I had a Heights 84' (?) aluminum crankup tower.

I don't remember why, but after a year or three, I took out of the bolts that was holding two
of the sections together...probably because it looked "rusty."

To my surprise, the bolt had "disappeared" to about 2/3 of the original thickness.  That's 
when I learned that aluminum "eats" steel for breakfast, lunch, and dinner.

I replaced all of the hardware with SS and never had a problem after that.

So YES, use SS.
