Was wiping down my interior, and when I opened the driver's side sun visor mirror lid, it snapped off! Wow, this thing is cheap. Luckily, I had an entire spare set of sun visors that I bought used from eBay years ago when the pass side visor wouldn't stay folded up. Does this thin plastic just break down from sun or heat damage? Anything to apply that will make em last longer? The mirror cover literally disintegrated.
