Well, I tried out my PB S&W and QD+ products this weekend. The S&W is pretty good -- might not be 100% or even 90% as good as a regular wash and rinse, for sure -- but it is quicker. And it`s nice to have a spray bottle available just for little blotches that may appear from time to time.
However, I have a problem with this board`s enthusiasm for QD+ and similar products. My argument isn`t so much with the product -- it works fine. But to really apply it correctly, it seems like it works best by letting it "harden" for a while on the car and then you wipe it off. This takes longer, although I don`t mind. But in this respect, it`s not much different than applying UPP or any other finishing product that asks to stay on the car for 15 minutes - 1 hour before you wipe it off.
Now, I know you can theoretically wipe QD+ off right away and this saves time. However, I`m not convinced that you get 100% of the benefits that way -- in fact, depending on how much stuff you wipe off, you could eliminate 50-90% of the formula by re-sopping it up on your MF towel. There are 3 different ways to apply QD+ listed on the bottle, so it`s clear that there`s no best way.
Still....I think it`s unrealistic to expect that you can apply a fresh coat of wax or sealant, QD+ or non-QD product or whatever in just a few minutes. Even if you exclude the "waiting time" from your calculations, the 2nd step of wiping the thing off does require some elbow grease. Whereas the S&W is 1-step cleaning instead of 2-step (wash, rinse) that we normally do, I`m not sure that if you use QD+ in a 1-step fashion that it`s what most of us want. If I`m wrong, vets, tell me.
Oh yeah...the darn spray bottle got the wax product all over places I didn`t want it to go. I hope it doesn`t hurt trim or plastic or glass, though I think I wiped it all off. Next time, I`ll use the regular nozzle and ooze it on by squeezing it.
