The car, that is. Due to the loss of my 3 car garage in the divorce, I now have a 2 car, so my new Muastang sits outside all the time. I'm in this car for the long haul, and am doing everything I can to keep it nice. I'm at the six month mark, and today I clay barred and waxed it. I've always used Chemical Guy's stuff, but I waxed it with thier Butter Wax when I got the car, and didn't feel like it lasted very long. The car is washed once or twice a week. I bought some Collinite 845 Insulator Wax, as I'd heard it was extememly durable, even when exposed to weather and washing. One bottle was $20, and two was $24.95, so I got two. As sparingly as you use this stuff, I hope I live long enough to use it all up! Its oily, and it smells bad, unlike most modern products that smell like fruit or candy, which I believe is on purpose as a motivator to get you to use more. It does come off fairly easily, and I guess time will tell on the durability. It did give the car one hell of a shine though! Anyone else ever heard of or used it?
