what does not defeat us, will make us stronger.
It is not a problem, it is a challenge.
Deflating, and now I have to go to the fridge and have a beer for you mate. Look, it has happened and there's something to be learned for the next project. Now you have a repair on your hands, so treat it as such and get on with it. You have the skills to have this playfield 100% - no need to rush.
From a purely technical prospective - have you called the manufacturer - so see if the paint was a "bad batch" or something along those lines ?
I look forward to the next update, with the playfield 100% and the reasons behind the reaction. Thanks for sharing - it is not often we see these kinds of posts that we can all benefit from.
