DP 4 in 1 - Mixup for QD -2 Thumbs ^

IMO, ONR>DP 4-in-1 in every way. And even if it is less effective (which it is not) you get DOUBLE the value with ONR because the dilution ratios of DP 4-in-1 are exactly twice that of ONR.

So to me, 4-in-1 might as well be ONR dilouted 50:50 with water and dyed orange instead of blue.
 
I have used the 4-1 as a QD and used it for claying and if you add a ounce of it to your favorite soap when you do a conventional wash it will make the soap slicker and leave the surface looking better.

This is a very versatile product and it leaves the finish super slick

Thats my favorite use for 4-in-1, as a wash additive. Makes any soap slicker, makes it easier to dry the car, and cuts down on water spots.
