WARNING: This page is about a different car, the 2021 Porsche Cayenne and 2020 Porsche Cayenne. However, it is still accessible from the selected car via links, so may be relevant.
Information
A 1-2 mm surface coating of adhesive residue is required to help new adhesive to stick.
Keep cut surfaces clean and free of grease and do not clean with cleaning solution.
If there is no longer a surface coating of adhesive residue (e.g. during body repairs), the affected area must be cleaned and treated with primer before applying adhesive.
Adhesive must never be applied to an unprimed surface.
Likewise, primer must never be applied to the adhesive residue.
Activator must be applied to the bonding surface after leaving it for more than 2 hours.
Information
- A drying time of at least 10 minutes must be observed between cleaning the bonding surface and applying primer! There must be no cleaning solution residues left on the body.
