What does everyone like for window sealant as far as durability and having the rain bead and run off at low and high speeds? I like Optimum's for durability but I like Adams for beading and run off. Optimum is a little pricey for how much you get. I was thinking of giving Gtechniq a try, I have heard good thing about it.
I havent personally used opti-glass but all my customers who have says its amazing. Use to offer adam's but when i ran out i stopped buying it and tried opti glass
