I'm a big DIY guy and I have spent at least a grand on there products not because I blew through them it's because I wanted to try every one of there products! The highest quality car care company by a landslide! If you guys have a dark car try there black light polish with there Black synthetic paste wax...lava luminous glow infusion is another great wax for all color cars ...and if you need a sealer there jet seal 109 is epic! Did I mention I love this company!
