I am restoring my first pump, a Gilbarco 96ER with sight glass. I want everything to look as realistic as possible but without gasoline the sight glass looks empty. As I remember when actual gas was being pumped the sight glass was red or blue depending on what gas was being pumped.
The question is ....What's the best way to make the sight glass colored red (for regular gas). I would prefer not to use liquid because of leaks, etc. Is there such a thing as transparent glass paint that I could use to paint the inside of the sight glass ?
Has anyone done this, or have a better method ??
