BTS is the best product I have found by far. I have a 2004 F-250 that had some water spots on the truck and windows. I could not find anything to get it out, until I found BTS, my truck now looks better than it did the day it came off the showroom floor. You can use this product for virtually anything, I use it to keep my boat seats in top shape. Not to mention the protective coating it gives me on my boat, all I have to do is use a damp cloth and wipe my boat after a days fishing and if anybody has fished the Red River in Bossier City La., you know you need all the protectant you get. Great Product and keep up the good work.
