What a terrible job, made even worse because it has been done under the banner of BMW. My theory on this is that they had it done by one of their in-house 'trained' techs who are usually a couple of guys who have had an intensive session at Thatcham where they have learned to use a reciprocating cutting tool (which, going by the images appears to be true in this case) and then get given a stamp on their CPD card based on some very, very basic training.
IMHO, it's subjective in that you might get someone who totally understands the process and is 'gifted' with a logical thought processor. Conversely - and more likely - is that you'll get one guy who rarely gets to practice these newly acquired skills on a car, but when he does, he cannot perfect it for lack of experience. There are many, many examples of these scenarios catching the BMW dealers out simply because the more involved jobs are just too much for them to cope with. The very little 'real' experience they acquire will be a mixture of easy jobs, or ones they've simply managed to get away with.

He tried with reasonable care to remove the scuttle panel which runs the width of the car but broke one of the pieces where the clips attach on the corner of the panel. He also broke a couple of the scuttle panel plastic rivet with screw insert type clips which hold the scuttle panel on the bulkhead side of the engine bay. There was nothing that could be done about this as the plastic clips and scuttle are nasty USA brittle plastic. He took enough care trying to get them off so I could not complain, it is just cack design and quality of plastic. He glued the corner of the scuttle and I got a couple of new rivet clips.
Clips break. They'll break if you're not careful, or they'll break if you don't 'pop' them in sequence. As much as the unexpected can happen, this can mostly be avoided by common sense, and/or experience. IOW, common sense suggests that you'll only make that mistake once??

In terms of breaking the adhesive bond around my factory screen, he used a special tool where he basically ran thin metal wire around the outside of the screen, around the adhesive bead. He then poked one end of the wire through the adhesive bead at the bottom of the screen and attached it onto a machine he mounted on the screen inside the car. The machine had suckers and stuck onto the inside of the windscreen. He then wound a handle on the machine and it wound the wire onto a reel, which pulled the wire tight around the screen bead so the wire cut through the adhesive bead all round the screen. The idea of this machine is that it does not cause any damage to the car or metalwork around the windscreen like you now have!!
Agree with the reasons he gave however, it doesn't mean to say that the method/technique he demonstrated is the right way, or that it (or any other way) is wrong. What you're seeing is a system being developed to minimise damage, and to reduce the risk of injury. The skill and expertise lies with the fitter/technician, always. But when you have an organisation where the majority of your staff are not experienced, or are a danger to themselves, etc, you'll come up with a system that is idiot proof. The system you have described is just that - anyone can use it. The sellers of such equipment will often show a promotional video of their IT guy using it to illustrate this. The average windscreen fitter is not skilled. The chances of him becoming experienced is inhibited by this blinkered view of how to do a job because much of the human element has been removed or replaced. The best example of this is the repair system used by the aforementioned. It does not allow human intervention insofar as if a break needs to be manipulated in order to fill the crack, you simply cannot by way of its design (you can't get in there) or by the way it works - it literally is a one, two and three step process; part of its name is '123'.

I talked to him quite a lot and he explained that Autoglass fitters are ABSOLUTELY FORBIDDEN to try and remove the screen and break the adhesive bead by ANY OTHER METHOD due to damage to customer vehicles and complaints. I remember he said they had taken all other tools they used years ago such to break the bead such as knives and cutting tools off of them to stop anyone using anything other than the machine.
What is also "absolutely forbidden" is to get the customer to help in any way and that he did suggests that he was possibly nervous, inexperienced or out of his depth. If his bosses found out about your participation, he would be having his head handed back to him.
Overall, I'd say he's done a good job of convincing you that the way he has gone about his job is the best - or better - way, but I think you should not base your opinion of your experience on this entirely. He's done well and projected an image of what his employer wants him to. I'm not saying he's done anything wrong, but he's merely done a good job of convincing you that you've had a decent job done.
