Is it really that bad? I've got a few alu stems with A2 and A4 stainless bolts, all installed with shit tons of grease. Not had a problem with corrosion... yet.
We have to use stainless coated fasteners at work into our aluminium castings because of this. Done a fair amount of work on it in the past . Have some great pics of aluminium being eaten away by it!
