Some of my favorites were not tested. Meguires NTX and Protect ALL are my current favorites. Both are liquids. Protect All, which is fairly unknown is worth consideration and Meguires NTX is also a wonderful product.
If you are interested to know more about Protect All here is their web site. It has a pretty big following in the motorcycle and aircraft world. Dustless and easy.
