However...any body damage cannot be “pounded out”. Aluminum doesn’t really dent, it stretches. The “fix a dent” guy, won’t. And yes, painting it is definitely trickier - generally, it requires absolute cleanliness and etching or epoxy primer.
“Frame” and suspension parts are forget it if they are bent or broken. Very few body shops in the US are qualified to straighten or weld an aluminum frame (welding/straightening aluminum is an entirely different, highly skilled, more capital-intensive process). Body shops that can actually work with aluminum generally operate in two entirely separate buildings, because the iron dust from grinding contaminates aluminum work.
Steel stretches too. The difference is you can pound out the steel and then "shrink" the stretched places by heating them red-hot with an OA torch and quenching it. If you try that with aluminum you'll just burn holes in it, and welding aluminum is something most body shops do not have the equipment or experience to deal with.
