EVOlved,
If you choose a bucket method then i would use 1oz of shampoo to 1Gal of water.
Foam method 6-8 water to 2-4 oz shampoo, depending on the size of vehicle you are washing.
Don't worry about the reactivating part of it, it only applies to cars with prior Nanolex coatings.
Our shampoo is the first product in testing since the other ones are sealants or similar and are longer lasting.
The shampoo is not a typical shampoo that will strip other coatings and therefor is priced accordingly.
Nanolex makes some of the best products i have ever tried and its my privilege to be a distributor for them, I'm a firm believer and only use our products for all my cars.
