What is Dot Matrix?
Most cars have a black ceramic 'frit' edge on the rear window. Sometimes this ceramic edge is straight and flat, sometimes it will have a dotted matrix edge. These black ceramic dots are quite thick on most cars and prevent the film from sticking to the area between the dots. This results in a whitish looking strip trimming the glass.
Typically this isn't very noticeable, however some cars have a wide band of dots trimming the top of the rear window. This area is so wide that the whitish looking area created is more pronounced.
Not much can be done about the narrow strip of dots going around the edges, other than letting the film dry for a few days and then pressing the film down onto the dots with your finger or a hard card wrapped in a paper towel. usually this will greatly reduce the whitish appearance. This usually doesn't work well for the wide band of dots.
There are a few options our shop offers with the very wide dot matrix area.
1 Vinyl The kind that vinyl letters are made from. We will trim a piece just big enough to cover the dots on the outside and apply it dry on the inside with the use of a hard card wrapped in paper towel. After it is applied we trim the excess off of the bottom edge by hand and then start the window film from that point. 98% perfect job $25.00.
2 Paint themThe dots can be left untinted, the film allowed to dry for a couple of hours, then painted. The best way to paint the dots is to use a flat black enamel spray paint. Mask off the tinted area and upholstery trim with plenty of plastic and masking tape. We make sure to get a good straight edge where the paint will meet the tint. 100% perfect $50.00.
