There was certainly no raw nerve hit on my end mate. As I said, your car, do with it as you please. The way you've done it is probably a good way to educate yourself that the 'official correct' way isn't always the best way.
I'm no mechanic and I don't profess to be. I'm just an average bloke who has done this job a few times without coming close to breaking or damaging anything, and without removing parts of the car I didnt need to. I don't see how pulling wipers off, separating foam and tearing seals is better simply because that's what the book says to do, when a bit of observation of the mechanics of it shows that there is a simpler and less risky way.
And I'm not sure what was holding your screen in, but mine have all come away by simply grabbing it with fingers. There's nothing else holding them in except the friction of it against the sides of the opening.
Anyway, as I said, if you're happy with the process and the end result that's all that really matters. But when you post on a forum looking for advice, expect some differing opinions, doesn't make us (or you) right or wrong
(Edit - posted this before I read last page re putting it all to rest, sorry. No more posts from me on this matter)
