I just put down Klasse AIO, then 3 coats of Klasse sealant and then a coat of Souveran wax. The AIO says it would last up to 6 months, The sealant says it will last up to 1 year, and Souveran says it will last up to 3 months. So since I put 3 coats of sealant on does that mean my sealant/wax job will last up to 3 years and 9 months? I am have kidding but how long do you think it will last. I garage my car every night.
