Made and tested in Arizona heat. Apply in direct sun, use a window squeegee to spread out a smooth, even coat. Next, leave it to soak in for 2 to 7 days, depending on when the last waxing was done. I soaks into the microscopic pores and fills them with clear, microcrystalline wax. This is not a rub-on . . .rub-off carnauba wax. It has been in use on Rv's, and cars in Arizona for 11 years. One 32 oz does up to a 35 ft length. Pick up near Hwy 17 and Indian School Road or I can ship it to you, add $5. Owners and detailing companies love it. Message me with questions anytime.
