Working with Porsche 2-component window adhesive: Hardening
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.
The window adhesive used hardens at temperatures of between → Minimum temperature: 10°C and → Maximum temperature: 70°C .
Hardening can be accelerated by heat (e.g. using a painting booth). The bead of adhesive you pressed out earlier can be used to check whether the adhesive has hardened properly.
Do not put pressure on bonded parts until the required assembly strength is reached.
