recommend varnish type for transparant acrylic
(OP)
I want to protect the paint on acrylic compass baseplates like these:

The paint wears of to fast and you have to replace them because you cannot read anything on them anymore.
I need the varnish to be hard (scratch resistant) completely transparent and should not yellow, should be completely weather proof.
I have tried so far with an MSA varnish from goldenpaint, but it was to soft and gets ugly even by scratching with a fingernail.
any recommendations for this?
thanks in advance

actually I want to protect existing baseplates which have the paint on the back as the most outside layer. So I want to put an extra layer over the back to protect the paint from scratching of.

note that the bevel in the middle needs to turn, so preferably it should be applicable locally, as in a liquid form or spray.
thanks for your help

Failing that I'd buy some clear varnish spray cans and try them.

To make it really nice, you will probably have to mill the shape, not shear/punch it, and anneal the acrylic after cutting.

Are you even a tradesman or handyman.
Of course fabricating a part from sheet then attaching it is more complicated than spraying a coating onto it, but ir also gives a thick solid protective layer.
The existing coatings may interfere with the process or may be damaged during further coating.
Engraving the surface of the acrylic before the original painting will protect the pain, that is if you engrave in only the areas to be painted then only paint in those recessed areas.

The one I got as a Boy Scout has the markings hot-stamped on the back face of the baseplate, then filled with paint.
Granted, it hasn't seen much use in recent decades, but the markings still look fine.
