Mathazar,
For having entirely renovated a Mata Hari, a couple of years ago (documented on Pinside), let me express my disappointment for you not trying to rescue the original playfield. The few defects you had on the playfield, were easily correctable (I and others have indicated the matching colors) and you could have instead practice at clear coating your repaired artwork.
You did a very nice job at installing the hardtop, but it will remains a hardtop (plasticky) and will never provide the smoothness and crispness of the original artwork.
I understand that a few destroyed playfield have to be salvaged with a hardtop, but in your specific case, I consider it a crime to not try restoring the original playfield. I am thinking about future generations (my kids love pinballs) and cringe at the prospect that a lot of decent machines will have been turned into a pale copy of what they used to be, due to the abuse of hardtops.
I know it is your machine and you are free to do what you want with it and even though Mata Hari has been produced extensively, these relics of the 1970's deserve to be restored like Museum pieces, whenever possible.
