Re: plexglass face mounting




"Plexiglass face mounting" means mounting ON the plexi or UNDER the plexi, face up? Either way, I'm surprised there's been no mention of plexi discoloring (clouding, yellowing) in time -- maybe not in 5 years, but surely in 15 or 20. Unless there's a new plexi that's "archival"?
