Review on 🚗 DuraGloss 921 Automotive Fast Clean and Shine Review: 22 oz. Product Analysis by Robert Wood

I use QD less and less, I switch to washing without water and without rinsing more and more often. When I need QD, I use it. I add about 20-25% Aquawax to this material to give it a bit more shine. Not necessarily, but I like the way it looks better. This stuff just works and looks good. The addition of a small amount of Aquawax makes it great. This also makes it very similar to the results I get with the DG 521. I'm not saying they're the same, but the results are similar. I use this material because I have it. For pure QD I would use that. For some shine that you can use often I suggest adding some Aquawax or using DG 521. Both 921 and 521 are great.
