My covers had been sealed before I bought the car. it was clear that the previous hands had not wanted to spend the extra time cleaning of the old sealer. Also from 35 years working in an engine laboratory for a major car makers R&E department, I know you have to let this stuff cure. My guys loved it because it gave them a rest !

By the end of September the car will have covered over 2000 mile in Europe with a good stint on the Autobahn. I have a tour booked, there will be no prisoners some will be pedal to the metal driving. Let's see what falls off ��
