It cuts fine with an exacto knife

I just dismantled my old control panel and noticed how the cpo from mamemarquees (now gamongrafix) is still in great shape with no scratches.
I will be ordering another cpo from them for my new cpo.

Thanks.  I'll likely go with GonG then.

Interesting.  Seems like the opposite of others experience.

Huh??

Plexi is harder a more scratch resistant than polycarbonate (Makrolon is the specific brand I used), so I'd say that is why he's surprised to hear someone claim the opposite.

Yes.  markronz said that his plexi cpo scratched but his poly cpo didn't.  Most everything I've read (here and elsewhere) says that poly scratches easier than plexi.

I've built several machines. I've used plexi a few times and poly for a majority of the machines. I prefer poly.

Plexi looks nice once it's first installed, but I've had issues with it curling up at the corners and dust getting in between the plexi and the artwork. I don't really have an issue with scratching with either one. It's in my home and it gets played by kids and adults. I don't ask them to be gently, but people are generally nice to the machines.

I think there is a little confusion in this thread, we are really talking about 3 option here:

1/8 acrylic sheet over artwork (Harder to scratch, a little harder to work with, Removable)

1/8 polycarbonate sheet over artwork (scratches easy, easier to work with, Removable)

8mil polycarbonate laminated to artwork from Game on Graphics/Mamem Marquees (very scratch resistant, very easy to work with, Non-Removable)

Ah, I see.  But why the difference in scratch resistance between 1/8 and 8mil polycarbonate?  Are they different types of polycarbonate (like say mild steel vs tool steel)?
