As a lot of people re-sell mylar, usually without a copy of the manufacturer's safety precautions, I thought it might be good to remind everyone using mylar: ALWAYS check it for pinholes before use. If you spot any, do not use it until you've closed the hole with a small piece of opaque tape, or a drop of lacquer. White-Out works well for this. The tape or lacquer will not harm the image at all. The filter won't have to be replaced until it looks like a polka-dot pattern, in fact. If the hole does not go all the way through the material, but is just a spot where the aluminum has come off the substrate, you can opaque it with a permanent black marker. Usually two or three "touch-ups" are required to get the ink opaque enough. If the sight of the dots offends you, do it on the back side.
