Actually, you don't mix the two together.
Directions:
Work on a clean, dry surface out of direct sunlight.
Apply a few drops of Part A to the included black applicator pad. Use sparingly.
Rub Part A over the entire vehicle.
Wait 5-10 minutes. The vehicle may look matte, hazy, or wet. This is completely normal.
Apply a few drops of Part B to the included red applicator pad.
Rub over the entire vehicle working in the same order that you did with Part A.
Allow the products to remain on the vehicle for at least 30 minutes.
Use the included microfiber towel to buff the surface to a shine.
Allow to cure for 24 hours before exposing to rain or other moisture.
Used it many times. Absolutely brilliant, durable.
