I have been a big fan of the Pro-Blend portioner for a long time. I would use the Pro-Blend portioner on thin liquids like Optimum No Rinse or some APCs/degreasers all the time. But, when I started using P&S Absolute rinseless much more often (which is thicker than ONR), the Pro-Blend portioner does not work well. So, I did a little digging and found the CarPro Measure. The Measure works extremely well with thick liquids like P&S Absolute and car soaps. My only small gripe is that the markings are more for metric than imperial measurements. The CarPro Measure has markings for both measurements but the measurements are in round numbers for metric and then the equivalent in Imperial is next to it such as 2.4 ounces

Huge notice only works with thin liquids thick soaps it will not work with.
