All the games in a Namco owned arcade that I was running had plexi installed
on them. It helped greatly in keeping the CPs clean and protected.
Dust washers on the outside, added more protection.
Drinks spilled often just ran off the sides, not causing major problems.
The CPs that didnt have Plexi often had artwork overlays that
lifted in areas.. cracked in others, warped and pieces broken off.
(mostly the overhang of the edges.. but not limited to it)
This created sharp edges, which were VERY uncomfortable.
They were also a nightmare to clean. As the oils and filth from hands
were ground in deeply. Some stains wouldnt come out.
Plexi scratches much less than Lexan. It however, is more brittle,
and can crack easier, usually when trying to cut the holes in it.
Rarely breaks when properly secured to the panel however.
Overlays arnt perfect. They dont bend well over the overhangs.
Glue that holds them down often fails over time. The overlay material
also seems to becomes more brittle over time.
You get used to the feel. Plastic is everywhere.. even on your
keyboard
A solution to some overlay issues may be to spray many layers of
automotive(?) clear-coat over them... to keep them protected,
and less lible to lift. However, Ive not heard of anyone doing this.
I agree that the look may be sacraficed when using plexi.. mostly
due to reflections affecting the way you clearly see the art and
colors. However, its very acceptable to most for the added protection,
lower maintenence, and longer lastability.
Another interesting idea may be to use something like
leather as a topper. May be much more comfortable
Tho Ive also not seen this done. Of course, art
would be limited at best for such an option.
