gauge cluster plastic cleaning

[JointTech]

any good ideas on cleaning the plastic without scuffing it up or removing the painted on labels?

Are there stickers anywhere to replace the writing if it flakes off?

I have a crack in one of the scrw holes on the bezel. Any good ideas on sealing it up? I was think just super glue it. there is no gap in the crack. then sand and high build primer the whole bezel. Im not going for a real stock look. the highbuild by itself will cover the crack but ill have to remember to barely tighten that screw.

On the gauges the black paint and labels are pretty good so I just need to do the needles. they have a strange crust on them so im going to try to sand it off without touching the gauge and then paint the needles carefully.
