Do PANEL IMPACT RATIOS Matter? (PRO SERIES #1) ft Bilt Hamber Auto Foam

In this 'Pro Series' video #1 we discuss the Pre Wash stage in more detail, and the importance of Panel Impact Ratios (PIR) when completing a Pre Wash of a vehicle.
There's an interesting demo, in which we used the foams at the recommended amounts suggested by the manufacturers.
We know that the wash stage is the stage which can cause the most imperfections in a vehicles surface, so getting the Pre Wash stage correct is of paramount importance to aid in having the safest wash stage.
In this video we discuss what PIR's are?, we see if PIR's make a difference?, and just how much if at all?
A lot of people think that more foam or thick foam equals a better pre wash. As much as this may be true to some extent there comes a cut off point where if the foam is too thick/dry, or adding too much product is just a waste of money, and knowing the optimum amount of product needed to get the best pre wash is what makes the difference.
To work out PIR:
a. How much product is needed once you know the flow rate of your system:
e.g. You establish a 12 litre flow rate, and you need 4% PIR =
12000 x 0.04 = 480 ml
b. You put a certain amount of product in your foam lance and want to know the PIR:
e.g. You establish a 12 litre flow rate, and you add 260 ml of product in your foam lance =
260/12000 x 100 = 2.16% PIR
