Many thanks for showing me this sealant. This product is not available in the UK, I will ask in the UK forum if somebody knows an equivalent that is available here.

I could import it, but this will take weeks to arrive and at least doubles the price.

UK readers can follow my quest here: https://f30.bimmerpost.com/forums/sh...6#post25092606
