The process takes 30-45 minutes depending on how many workers.
Zahid the owner is friendly and helping when discussing pros and cons. This is important as the 100% coverage requires them to drill holes. I personally have a problem with that and am opting for a less than optimal solution.

Truth is we will need to keep the car for 10 years to really know if this is the best solution. So for now I go on good faith.
