Differences between 4*UPP and EXP?

I think this "how easy is it to apply" questions are kinda irrelevant. All of these products are liquids, and they apply pretty much equally easy, depending on whether you use a MF towel, an MF or PVA appliator, with or without some water spritzes.

The DIFFICULTY is if you need to let it sit a while. For most of these, either it sits by choice -- 30-60 minutes for UPP or EX-P -- or because we do the entire car before wiping the first applied (SG, etc). Either way, once these things harden on the car, it takes a bit of elbow grease to take 'em off.

Even items that it says can be applied and the taken off immediately, before drying, I usually like to give it a few minutes.

I used Eisenstaz 1Z and was a real liquid, not any viscous liquid, so it applied alot easier than these other formulas. But to me, compared to all the other work in detailing a car, that's a miniscule savings. And again, even though I think that 1Z coulda been wiped off immediately, I let it bond to the car a few minutes before I wiped it. So once again, a little elbow grease was applied.

Bottom line is, all these liquids are EASY compared to those lousy waxes and pastes we all grew up with in the 1980's by comparision.

And taking off these things with a MF is a helluva lot easier than regular towels. I remember it used to take me 45 minutes to take off the coats of Liquid Glass on my Vette 15 years ago. Today, with a MF towel, 15 or less.
