Everyone -
First, I will never recommend a product, procedure or service to anyone that I have not personally tried or used and that performs to my satisifaction. Needless to say, I do not impress easily. With that said, I am impressed with this product. I used it again last night after driving 550 miles in the rain on Sunday and Monday. What can I say - it works. After using it last night I used Turtlewax Ice Detailer and the 4Runner looks great. Does it look as good as a show car? No, but it looks great from a few feet away and even though I have black, there are no more scratches than it had when I used old hose and bucket method. If anything, it has less.
If my truck has caked on mud, sand or heavy salt then I just use a hose first to get the major stuff off before using this product. For normal day to day road grime, dust and pollen I do not hose first I just use the No Rinse. For tar, you use a solvent like bug and tar remover. I really have not tried bugs yet but I'm sure my "soak" method will work. This method is simply getting a wet rag and saturating the front bumper, which works by "soaking and softening" the bug guts so they come off easy. Probably the best part of this process is having no water spots as you immediately dry the panel you just washed. That and using a cool bucket with two seperate compartments!
