[Shop-talk] Rivet Steel to Aluminum

[Rush]

We need to attach powder-coated steel to the outside of a painted 
aluminum truck body. I don't want to set up a galvanic reaction and I've 
never pop riveted anything into aluminum.
-How do we prevent galvanic corrosion?
-Are there special pop-rivets or tools for putting rivet into aluminum?

The truck body is held together with some large diameter rivets, but I 
am guessing they had two-sided access when they assembled it. We only 
have access from one side.
