instrument cluster repair what glue to use

But if you use ABS cement on ABS, PVC cement on PVC, Polystyrene cement on Polystyrene, etc... you get a bond very similar to a weld. All those 2-part adhesives and epoxies are good, but nothing will ever beat the correct cement that is matched to the material.

Yea you are right but your going to have a lot of slightly used tubes of glue or cans or whatever, this stuff from Devcon I got for a ABS fairing on a rare sport bike and did all the repairs and never had 1 crack, I have glued aluminum to steel, fiberglass, and never had a failure that's all I can say
it's just my experience with different glues and this stuff works great for me.
