A dot-matrix window has a raised, black-colored dot matrix pattern painted on the glass, usually in a wide area at the top of a back window, which are in five to six inch rows. When tinting over these dots, sometimes air pockets can result, leaving it looking messy and discolored. There are a few ways to eliminate this problem.
Tint the window as you normally would, covering the dots with the tint.
Remove as much water as you can from underneath the tint film at the dot matrix with a squeegee.
Carefully peel down the window film from the dots and squirt a bead of a stationary glue such O'Glue on the area where it meets the bottom edge of the dot matrix. You can also use a sealant such as Magoops and squirt a bead of the sealant across each row of dots on the matrix.
Lay the film back across the dots.
Wrap a Bondo card in a paper towel and use it to gently squeegee the film, working the bead upward horizontally in one direction only to smooth it out. If you've used the glue, stop just before you reach the top so the glue won't come out. You can just use a squeegee if using the Magoops.
Squeegee the glue out after all the glue is at the edge of the film, catching it in the paper towel. Wipe off any excess glue from the tint with a paper towel.
Tint the window as you normally would, but leave the tint off the dot matrix area.
Allow the film to dry for a couple of days.
Mask off and cover the tinted area with masking tape and plastic. Make sure to leave a nice straight line at the edge of the window tint.
Paint the dots with a flat black enamel spray paint.
