Good starter
Style: KIT
The chemicals are 5 stars, because the Chemical Guys make great and effective products. And they always smell good, but the taste doesn’t match the smell. I wish it came with other chemicals in the kit. But honestly go buy them one by one and get what you need.

Good quality car care kit
Style: KIT
This product was specifically asked for by my adult son. Upon opening, it had leaked (it was a gift so I did not open) but he went ahead and used it. Good quality, car care product.
