If you are talking during a night of tinkering, a lot of pleasant nonsense will come by. But sometimes you have a joint "Oh yes, that's interesting" moment.
Such as when changing a pair of motorcycle tires. This is easiest when both wheels are dismantled for a while.
And that is safest if a spare wheel is placed in the front fork.
But the conversation wasn't about that. It was about gluing a car window on 'new' paint.
The approach was that it was not handy. A glued window actually contributes to the stiffness of the carriage of a modern car, but also to that of a classic car. one of the attendees was able to report that when a window was mounted on a freshly sprayed surface, but was declared dry, the lacquer layer would dissolve, that there would then be blistering in the lacquer that came into contact with the window kit, often in such a way that there is detachment. The solution is to tap off the 'track' where the window is to be glued before spraying.
To make fresh paint work 'windscreen-resistant', a drying time of at least four days should be used.
And that is a period that we, as enthusiasts, can easily handle the owners of a professional car damage repair company.
A funny fact anyway
In the factory, the window is also glued almost directly to the fresh paint. There is no time to wait for 4 days. After drying, we too stick the window directly onto the fresh paint. With fresh paint and a good window kit there is good adhesion. Actually better than with old paint. You should always treat this with primer for optimum adhesion. It is a waste of your work not to spray the window frame.
