NSP GL

TOPICAL GLASS CORRECTION INSTRUCTIONS
Topical glass correction is for removing any type of contamination that is bonded to the outer surface of the glass. This can include things like water spots, road film and drizzle stains. Topical glass polishing can be done by hand or machine including both orbital and rotary polishers.



1. 1. APPLY

   Apply NSP GL in a circular pattern around the face of a Rayon or felt polishing pad.

2. 2. SPREAD

   Place the face of the pad against the glass. Turn buffer to medium speed and spread the product over the glass.

3. 
   
   
   
   
   3. HIGH SPEED BUFF

   Once product is spread, turn buffer to the highest speed. Make 6-8 overlapping passes over the glass to remove any water spots, traffic film or drizzle stains.

4. 4. WIPE & REPEAT

   Wipe off any residue and inspect the results. If desired results were achieved, proceed to the next window or area. If results were not achieved, repeat steps 1-3

SUB-SURFACE GLASS CORRECTION INSTRUCTIONS
Sub-surface glass correction is for removing defects that are below the surface or in the glass. This can include swirls, scratches, wiper marks, tiny pits, scuffs, and miscellaneous abrasions. Unlike topical glass correction, sub-surface glass polishing can only be performed by machine. The human hand is not powerful enough to correct sub-surface defects in glass.



1. 1. APPLY

   Apply NSP GL in a circular pattern around he face of a Rayon or felt polishing pad attached to a machine buffer./li>

2. 2. SPREAD

   Place the face of the pad against the glass. Turn buffer to medium speed and spread the product over the section of glass.

   3.HIGH SPEED BUFF

   For rotary buffers, turn the speed setting from a low RPM to 2800 RPM. For orbital buffers, turn to the highest speed setting. Make slow overlapping passes in a crosshatch pattern.

4. 3.1 BUFFING TIPS

   How long or how many passes you’ll need to make depends on how deep a defect you’re trying to remove. For shallow wiper marks, you may need to buff the glass for as long as 20 minutes. This time will be longer for deeper wiper marks, swirls, and scratches.

5. 4.WIPE & REPEAT

   Periodically wipe away NSP GL residue from the glass and inspect. If desired results were achieved, move to the next section and be sure to overlap slightly into the previous section for optimal UMR (Uniform Material Removal). If defects remain, repeat process until desired results are achieved.

• An interface pad is strongly recommended when using NSP GL to reduce strain. An interface pad will create cushion, flexibility and smoother action between the surface and your arms. Recommended pads: 5" | 3"

• Sub-surface glass correction is best done and faster accomplished with a second person assisting. Having an assistant to continually add water to the glass will help to achieve better results, lubricate the surface for better maneuverability and keep surface temperature cool. An assistant will also allow you to take turns buffing the glass, helping reduce any fatigue associated with extended machine correction sessions.

• For windshields and all other larger glass windows, we recommend dividing the glass into smaller, more manageable sections. A windshield, for example, can be divided into four quadrants for better manageability.

• Depending upon the design and placement of the wiper arms and wiper blades, you may need to find a way to move these out of the way. An easy way that works for a lot of cars is to simply use a roll of painter’s tape placed between the wiper arm and the car. This will hold the wiper arms away from the glass so you can run the buffer and spinning glass pad all the way to the bottom of the windshield without hitting the wiper arms.
