Installation Instructions

Tools Required:

• Cleaning Cloth / Alcohol Wipe

• Adhesion Promoter (Some Products Include)

• Plastic Scraper (for Bubble Removal)

Installation Steps (General Reference):

1. Clean Sill Surface: Wipe the sill area with a cleaning cloth to remove dust, grease, and old adhesive residue—ensure dry and clean surface

2. Apply Adhesion Promoter: Wipe along the installation path with adhesion promoter, wait approximately 1 minute

3. Peel off Adhesive Backing: Remove the 3M adhesive protective film from the back of the sill protector

4. Align and Stick: Align with OEM sill curvature, press from one end progressively

5. Press Firmly: Use palm or scraper to press firmly, ensuring tight adhesion and expelling air bubbles

6. Check Installation: Confirm no edge lifting, tight fit with sill

【Professional Tips】:

• Avoid car washing and rain for 24 hours after installation—allow adhesive to fully cure

• Winter installation tip: Use a hair dryer to warm the adhesive and sill surface for better bonding

• Confirm position before installation: Sill protectors are front/rear specific—some products have left/right markings
