JWF - Micro Edging

Micro Edging

Micro-edging is performed on side door windows to give the appearance of having no film edge on the glass whatsoever. This technique will eliminate light gaps and provide a factory-installed tint look.

Tools Needed: Flat single-cut file, Heat gun and Tape (if necessary)

Cut your pattern 1/8
Step 2 – leave 1/8" of extra film at edges
File in an upward motion at a 30 degree angle.
Step 5 – use a file with fine teeth

Use finger to check edge
If you are working on a framed side door window, cut your film pattern leaving 1/8" of extra film over the top edge of the window.
If you are working on a frameless side door window, cut your film pattern leaving 1/8" of extra film over the top edge of the window, and 1/8" extra film over both side window edges.
Install film pattern per side door window installation instructions and let film dry for about 30-45 minutes (we suggest you work on the rear window while waiting).
To speed up the drying process, you can use a heat gun on the outside of the side door window to warm up the glass and make the film anchor quickly. Remember not to overheat the glass. This causes the ends of the film to wrinkle and will ruin the process.
Once the film is anchored to the window, use a 1/2" wide, flat, single-cut file with very fine teeth to rub along the top edge of the glass (and sides if working with a frameless window).
File the excess film off. Always file in an upward direction and at about a 30 degree angle.

Important Note: Since you cannot roll up the side window when you micro-edge, you will need to allow room for the film at the bottom of the window. If working with felt gaskets, tape them back.

Once completed, carefully use your finger to check along the edge of the glass to be sure you have removed all excess film. Material left hanging over the edge will cause peeling of the film as it ages so be sure the edges are clean.
