HAHAHA Just Kidding on that one, but welcome to DC
AIO is a paint cleaner that has light polishing characteristics and a bit of protection
UPP is a sealant that has an ultra gloss shine to it and great protection
Liquid Souveran will give a great shine and moderate protection
Personally----
--Poorboy's Polish with Carnuba is like AIO on steriods. It's less expensive, buffs easier, can be used in the sun, and overall, I have achieved better results with it.
--UPP is a great sealant to have on the shelf!!
--Liquid Souveran is good. I like the paste version better, and more so, I like Trade Secret paste wax even better over UPP as a topper.
--From THE SOURCE, TS is made by Pinnacle and is the same formula......$35 vs. $70 for the same product....in my opinion, it's a no brainer!
No offense Nick but I think Klasse AIO offers more than a "bit of protection". True enough, it doesn't provide the look of the other products mentioned, but as a base coat to be topped with any of the other products it simply cannot be surpassed. I've been using AIO for years and found it to be extremely durable (up to 6 months or more) even up here in Michigan. Plus, it can be used to clean an seal virtually any automotive surface with no staining.
Don't get me wrong, those other products are great too, and I use them all with the exception of Liquid Souveran. But to me it just seems wrong to compare Poorboys PWC and Klasse AIO. They are two very different products with different purposes.
Just my 2 cents.
