When applying a 2nd coat, to get the full effect of the longevity we recommend going through the whole process of the dish soap method to give you a clean slate to work with. You can clay bar too if you want, but dish soap wash should be sufficient.

We recommend doing this since you will be using Hybrid Wax in between coats. Since the Liquid Wax is super long lasting, if you put it over the Hybrid Wax, it will degrade at the same rate.

When you put the Liquid Wax first, then spray the Hybrid Wax, once the Hybrid Wax starts the degrade, the Liquid Wax will still be there.

-- Then you just top it again with a new layer of Hybrid Wax.
