Working with aluminum is really not that difficult. It can be bent, beaten, hammered, ground on, welded and sanded just like steel. It's for the most part actually easier to work with then steel. It just requires slightly different tools and technique.
If aluminum takes off, more body shops will get the tools necessary to work on aluminum.
