Well, picked the Cali up this afternoon - very happy. 18% over VW privacy glass provides near complete privacy when looking in from the outside, and not too much of a darkened interior.
The company said this was about the 15th Cali that they had done - they already had the templates for the T5 and T6 - and completed the work in about 3 hours.
Work was done in their shop. Slightly dearer than other companies that can come to you, but highly recommended.
