“I had a crease in the hood, from a blown over aluminum extension ladder, and I was happy with the repair.”
That’s Pretty Darn Good Work! A hood especially (You can see it from inside the car!), and any horizontal surfaces are tough because reflection really shows the imperfections. You can usually get away with more on a vertical surface. Color matters. Some are more forgiving than others.
I managed a body shop for a couple of years (unfortunately). What it comes down to usually with body work isn’t whether a repair can be done a certain way or not, but the cost involved from one method or another.
Labor is becoming an expensive commodity. That trunk lid (deck lid) would require enough work, either from conventional body repair or PDR that a cheaper route would probably be replacement, especially if a decent used part was available.
I own a car that had PDR (not perfect in this case, but remember I managed a body shop). It was a door ding and light was reflected down, not up to the eye.
I’m not opposed to PDR because I hate to alter the original paint job, but sometimes, for certain repairs, it’s not practical.
I’d listen to a trusted body shop on this one.
