Had a mirror acrylic on a strat copy and it crazed and scratched up over time. Swapped it out for a brushed aluminium one instead.

On my 1st Explorer it need a repair job that required a repaint and used the black Paul Stanley Iceman as inspiration. Ended up getting a 5 mm thick glass mirror cut in the main triangular shape and scrapped the rectangular bit between PUP's, plus had all the holes drilled. Looked awesome and had tons of fun catching and bouncing stage lights into the audience. Sadly over time lots of sweat got into the edges and it started to tarnish. Sold it off before that took over.

Would I do it again? Dunno, maybe gluing a thin broken mirror mosaic style and then coated in epoxy resin to seal it off might work? Would involve more time and money than what I have available at present.
