What is a good source in Northern California for 1" thick clear acrylic panels? Frosted on one side - can we do that ourselves?

Every major urban area has plastics shops and dealers. However if there is nothing in the local yellow pages you can try McMaster-Carr online.

From contributor S:
You can decide if it's appropriate for your project. A graphics shop can supply or apply a film that provides a very good facsimile of etched or frosted glass. It works great for temporary exhibit type stuff or can be sandwiched to prevent scratching for more permanent use. Seal/channel the edges if it's exposed to anything that might get in there, dust, water from cleaning. Most folks that look at it frankly will not see the difference.

Also, I bought a spray can of glass frosting at one of the box stores and tried it on plexiglass and it worked great. I've also hit plexiglass with a random orbit sander using 100 grit paper for good results.

From Contributor S:
I don't know where you are, and Northern Ca is a pretty big place but TAP Plastics, Concord would be your source for the material and any fabrication. Better have a good bank account balance though!

I have a sign shop next to my shop. Apparently sign making materials are a totally different ball game. I often cut aluminum on a PVC core for them. Perhaps a sign shop could direct you.

From contributor K:
Cope Plastics has a lot of locations E of the Divide. 3Form might be closer, but I wouldn't choose only for that reason. Wherever you choose to buy, be sure to ask about packing and shipping cost. As Contributor H said, you can sand it, but I normally use a lot finer grit.

Now that I think of it I believe Contributor K is right. It was most likely more like 220 to 320 grit that I used.

From contributor S:
After you guys sanded the faces did you have a problem with fingerprinting or collecting dirt or smudging when cleaning? Etched or blasted glass and clear acrylics we always put another glassacrylic sheet over the etched side. I learned the hard way.
