What color scotchbrite pad is used to scuff the pinchweld?

The pinchweld, which is the area where the windshield glass meets the vehicle body, must be properly prepared to ensure a strong bond with the adhesive. The red or purple Scotch-Brite pad is designed specifically for this task. Its texture provides the right amount of abrasion to clean and scuff the surface effectively, allowing the adhesive to adhere better and ensuring a secure installation.

Using the appropriate color pad is crucial because each color corresponds to a specific level of abrasion. The red or purple pad balances sufficient cutting power with the ability to avoid excessive scratching, which could compromise the integrity of the pinchweld surface. This attention to detail is essential for achieving optimal results in windshield installation.
