I discovered the brand products by purchasing this kit. I think I will never buy another self care product brand. Each product is quality. The shampoo provides wash and shine, here are some tips: After scouring the pressure washer, mix a little of this shampoo (no need to put tons) in a bucket of warm water, clean by area (eg just the roof) with a microfiber glove, wash immediately this zone pressure washer, and rinse the glove in a second bucket (very important technique for 2 buckets do not smear the contents of the first bucket and scratch the bodywork) The clay gum is miraculous! it removes tar particles, glue, insect ... on the body without scratching. You have to moisten the area to be treated with the dedicated spray, I recommend also to dilute the product with deionized water as the bottle is empty quickly! gum rinse under water and knead for multiple reuses. 2 sponges used to apply the polish or wax more easily than cotton wool as I used to. After applying the polish or wax, 2 microfiber give excellent results, they are machine washable and can be used for other tasks. Against by even folding in 4, it is quickly run clean microfiber surface, in the case of the complete renovation of a car. So wash and dry microfiber repeatedly to resume work. The polish is very effective and leaves no traces when once with microfiber towels. In my opinion, the 300ml bottle will treat at least 2 cars. Same for the wax 175ml bottle at least 2 cars will be processed. The wax provides extreme shine and is very fragrant! These two products can also be used to renovate the micro-striped plastic and tarnished as optical headlight. I highly recommend this kit even if the price is a little high.
