How To Restore and Detail an Original Gauge Cluster

[CousinTone]

I realize this is an older post, but being the standard for gauge cluster rebuilds I had a thought as I was reading in prep7for my attempt.

My turn signal tubes are shot and there was some discussion of aluminum taping the inside for increased light output. Looks like the heat generated from the bulb(s) and melting the plastic indicator gel.

What is everyone’s thought about using aluminum tubing with vent slot/holes along the top and using those in place of the paper tubes? I was also thinking of also polishing the interior to maximize the light transmission with a Dremel and the little polishing kit. Does anyone have any thoughts logistically or any other issues you may see, proceeding with this experiment? I’ll document my project and post once complete but wanted to solicit input considering the collective knowledge on this board is second to none. Let me know, thanks in advance for your input. Tony
