⚠️ Installation & Safety Warning: Replacing a secondary door seal requires meticulous surface preparation. CRITICAL:

One-Time-Use: The old seal MUST be discarded. NEVER attempt to reuse or re-adhesive the old seal.
Surface Prep: Clean the mounting surface with IPA (Isopropyl Alcohol) wipes and wait 1 minute for complete drying before applying the new seal.
Drain Holes: Ensure the drain holes are at the BOTTOM of the door and the open edge faces INBOARD. Incorrect orientation causes internal door flooding.
No Stretching: Apply the seal without stretching. Use a seam roller to ensure uniform adhesion along the entire path.
Glass Run Clips: You may need to release the glass run channel clips (x4) to access the seal ends properly.
