Support for local industry is by all means OK... but do they support us?
Over the years I did exactly this (I am (still) electronics engineer, and my first instict ALWAYS was to try locals for PCB manufacturing and assembly... but very often I did not get the quaity and prices easily obtainable from companies overseas (Taiwan, China...).
As for recoating mirrors, I have Coulter Optical 10", I bought it in mid '80-ies last century... and after 35+ years it is still quite OK, apart from couple of scratches which do not (visibly/significantly) affect the image quality.
Theese days I can probably buy the better mirror of the same size from GSO for cheaper price than recoat the existing one...
However, if the price for recoating is halved from what it is now, I woiuld't hesitate to go for it.
