Customer Rating: Summary: Recommended Comment: Great cleaner/polish. Must be used on a cool surface in the shade or it is difficult to remove. I use carnauba wax as well as acrylics and polymers on different vehicles I own. Simoniz is a good all around polish for your daily driver. Must shake bottle very well to mix polish before using. Product is thinner than most other polishes you find on the store shelves, which I find makes it easier to apply. I normally use a random orbital for application (terry) and removal (micorfiber) and then will buff (synthetic wool)for a more brilliant shine. Good longevity and durable shine. Good value for the money. Customer Rating: Summary: Simoniz Liquid Diamonds Comment: Found this product hard to wipe off. Smeared car finish and required a lot of effort and still did not not come off entirely. Not recommended for exterior vinyl trim - ran off on to car finish and smeared further. Would not buy again. Customer Rating: Summary: Excellent product with multiple uses. Comment: You can wax your whole car in about 15-20 minutes; a very nice product in my opinion. It also works great on interior surfaces. I use it exclusively with a microfiber towel. Customer Rating: Summary: excellent shine and easy on and off Comment: This is one of the best auto waxes I have used. Just wipe it on and it wipes off just as easy. The shine is very intense and is comparable to liquid glass at half the price. Also, great protection against environmental fall out and is simoniz system 5 approved.
