It's like any other degreaser as far as I can tell.. none of em ever REALLY work as well as you wish they would. I found that using a cheap $10, 1 gallon pump sprayer works great with it. It'll deliver a much more even and thinner coat, instead of just spraying a whole bunch on with a handheld sprayer that is all just gonna run off anyway. Makes the product go a lot further, and makes coating and recoating a lot quicker and easier.. the wand on the pump sprayer is great for reaching areas, and the adjustable tip can get you a real nice fine spray instead of wasting half of what you bought.. been on a pump sprayer kick myself, and just bought another to keep wheel cleaner in. Bought a gallon of concentrate Meguiars wheel cleaner that I just do a 50/50 mix with water.. much better with the sprayer, instead of buying individual bottles that only last 3 washes before being empty from reasons stated above.. the $10 investment in a pump sprayer is well worth it IMO for the individual chemicals you use a lot of.
