I've done a few Ultraclear versions and got it down to a fine art.
1. Be calm. Allow youself plenty of time. If you make a mistake, take a deep breath and start again. Don't rush or you'll end up ruining the film. Even though I've done this several times, I still allow myself half an hour.
2. Trim the narrow edge off an old credit card so it has a straight edge with sharp corners, and get some screenwipes or lint free cloth.
3. Do the fitting in a steamy room. I use the bathroom with the hot shower going. This drops all the dust particles in the air and elimates static which attracts dust/fluff to the protector.
4. Wash and rinse your hands thoroughly to remove all grease and soap.
5. Clean the PPC screen with a screenwipe then barely damp cloth. The humidity from the steam will help you to get a mirror finish.
6. Wash the protector under a warm running tap until thoroughly clean. Hold by the edges to avoid fingerprints and flick several times to remove excess water. You will end up with a few tiny droplets of water left that you can't shift. Don't worry as these help the sealing process. Don't wipe them off as this will just load it up with fibres!
7. Apply to PPC screen middle first. Immediatley wipe out bubbles by sweeping you finger from the middle to the edges. Smooth out firmly but lightly with the credit card using the sharp corners to expel air and water from the extreme edges.
8. If the protector is not straight, so the screen surround is fouling the edges, DON'T force them down - you'll just permanently distort the film so the edges will never lie flat on the screen. The tiny water droplets trapped under the protector may allow you to slide the film slightly so it pops in place - if not, peel off gently taking care not to bend the film, and start from scratch again - that means right back to the cleaning stage.
9. Once you've got it lying flat, smooth any small bubbles out with the credit card. Don't apply too much pressure as this could scratch or cause the film to move. Instead, use light, repeated strokes.
10. Wipe gently round the edges with the cloth to remove any excess expelled water so it doesn't find it's way into the device.
10. The little bit of moisture under the card will dry out within 24 hours. Resmooth the film regularly in that period with the credit card, to eliminate any small bubbles, or lifting of the edges, that appear as it dries. If you have to use the device, carry the credit card with you for the first couple of days so you can smooth it immediatley before any dust gets under the edges.
11. Keep the backing films in a safe place. You'll need these to gently slide under the protector shoud you ever need to remove it and re-apply.
Result - perfectly clear protector that is virtually invisible.
