Yes, we recommend applying our Liquid Wax first because of how long-lasting it is.
Since our Liquid Wax is a long-lasting full synthetic sealant, it only needs to be applied 1-2 times a year.
If you apply it over top another product, it will cause the Liquid Wax to degrade at the same rate.
When you put the Liquid Wax first, then spray or apply something on top of it, such as our 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.
Our Liquid Wax needs to be the very first product applied to your vehicle.
A clay bar would be the best way to thoroughly remove any old wax/sealant.
Using regular dish soap mixed with water as your clay lube will also help to remove it. (also saves a lot of money instead of using regular clay lube)
If you don't have the time or patience to clay bar your vehicle, dish soap and water should be sufficient to remove all your old wax/sealant.
