I'm trying to use SIO to protect gold coated mirrors. I'm putting down chromium then gold after a reasonable glow discharge. I then put down SIO (cold). My problem is that the SIO is lifting from the gold after a few weeks (or less) at atmosphere. It starts looking like orange peeling on paint. I can then actually wipe the SIO right off. Any suggestions?
