The dent thing is called a 'paintless repair' where the paint is not damaged but you have a dent. They get the panel back to shape by voodoo it seems. The guy who owns the repair centre is a bit in awe of this guy, who he gets in when he has a full day of paintless repairs to do.
I should also say how pleased I am with the colour match of an unusual colour "Honey Gold" on our car, where it did need paint. Press photo of my car in that colour below
