Step 1: Window Preparation
Use a grease pencil for marking on the window. Disregard the two small holes in the window tabs-they are for manufacturing purposes and should be trimmed off.
Step 2: Trimming and Final Fitting
If possible, create or use a template of the window opening for accurate sizing. Trace the template onto the OPTIC ARMOR and cut along the line, staying slightly outside the line for adjustments. Use a power planer and hand grinder for precision fitting. Sand edges smooth with an orbital sander or sanding block.
Step 3: Blacking Out (Optional)
After fitting, the window can be blacked out for adhesive application or aesthetic purposes. Sand or blast off the coating where blacking out is desired to expose the raw LEXAN. Mask the area with 3M Super 88 tape and follow the steps to sand or blast the coating clean. Apply 3M window primer after coating removal.
Step 4: Fastening
Mark fastening points at least 1/2" from the window edge. Space fasteners every 4" for most applications. Use countersunk flat-headed cap screws-DO NOT USE RIVETS. Tighten fasteners from the center outward and use locking nuts on the backside to secure bolts. Avoid over-tightening bolts.
