Preparing bonding surfaces: Cleaning

WARNING: This page is about a different car, the 2016 Porsche Macan and 2015 Porsche Macan. However, it is still accessible from the selected car via links, so may be relevant.

To prevent possible grease residue from spreading onto the surface when sanding down the surface until bare at a later stage, clean the bonding surfaces using a lint-free cloth soaked in isopropanol or acetone. Leave cleaned surfaces to dry for 15 minutes.

Then clean the bare bonding flange areas using a lint-free cloth soaked in isopropanol or acetone until there are no more residues on the cloth.

Information

After the last cleaning step, adhesive must be applied within 4 hours to prevent it from getting dirty again and to prevent an oxide layer from forming on the aluminum material. If adhesive is not applied within 4 hours, repeat the preparation process.

Leave cleaned surfaces to dry off for 15 minutes; the bonding surfaces must be completely dry.
