No it’s not. 90% of them have never seen the inside of a bodyshop, let alone worked in one. They buy a franchise, get a few weeks “training” and they’re qualified. And the big boys dictate the standard of the work, the customer does not, with clauses like “as long as the repair cannot be identified by a lay person from 3 metres, it’s a pass” or words to that effect.
Also, they’re worked on outside, even worked on when it’s raining without putting up a gazebo (I saw that this week in my road - another triumph of Chipsaway (“Like it never happened” my ass!) and with that the paint can get contaminated with dust, water et Al.
They overcook the paint to save time, which means the outside of the paint dries but the inside remains tacky and that can cause crazing and shrinkage. And boy do they overcharge too. Yeah, a slight scuff on a bumper which hasn’t damaged the plastic is one thing; in regards to the subject of the OP post, forget it.
