Painting multiple plexi signs at once?

If you want get the paint off the edges of plexi quickly without getting you tools, grinders or sandpaper all gunked up, then try this.

Cut your plexi and sand the edges. (I just use a grinder) Leave on one side of the protective paper and put the graphics on the other. Then paint them. When dry take a straight edge razor, (it's easier if you have the forward facing holder w/ the straight edge), hold it at a 60% angle and scrape across the edge a few times and bamm your done.
