Sanding Polycarbonate for Frosty Effect

I did this at TechShop Menlo Park. http://www.techshop.com

These large sheets of polycarbonate are to be sanded down for a frosted effect to be used in the construction of large art light-boxes.

The shiny surfaced sheets are revealed by peeling the protective layer from each side.

Using an air rotary hand held sander and 40 grit sanding discs and protecting the face with a dust mask we indulge in hours of making circles on this piece of plastic.

We pause for a quick break to hear some short but very poignant wisdoms from a book.

We roughed up the surface enough to have no more shiny spots. Now we continue to smoothen and frost our surfaces to perfection.

Note: this takes a long time and is pretty hard on the body. If you have a sand blaster, I highly suggest using it for quicker and better results.
