The Porsche waterproofer was a stand alone product. Haven´t seen them in a bundle either.Was the Porsche brand top protectant a kit with the cleaner? What process did you use as I'm looking to do my top soon and haven't decided which product to use.
I am kinda semi-pro detailer so I usually stick to a few favorite brands like Koch Chemie, Gtechniq etc. but wanted to try this for the roof on the Boxster.
Cleaned the top with Chemical Guys Green Clean (all purpose cleaner) and used a brush along the seems. Was kind of dirty as I rinsed off the soap. Sprayed 4 coats of the waterproofer product - allowing it to dry in between. Looks greet so far - will be interesting to see how long it lasts. Anyway - I usually never ride the Boxster when its raining.
