Saw a magnetic phone mount at Costco last week.
Did you paint the steel where it comes in contact with the aluminum? If not, in a few months/years it will start to react with each other, called galvanic reaction between the steel and aluminum. You will see the white powdery aluminum corrosion...
I have a sheet of aluminum I plan to use on the top of my roll cage, with steel ribs/supports 16" o/c. I will use rubber innertube between steel and aluminum to isolate (both for sound and corrosion control), and if I get real picky, stainless steel fasteners. Stainless does not react against aluminum.
Might be picking the fly **** outta the pepper, but it's info worth sharing.
