When I did my Tahoe with CQuartz UK, I applied with the Carpro Foam Block, and MicroSuede Sheets, and had some extra sheets on hand (Bought 16x16 Sheets and cut them into four 4x4 sheets.)
Of course I did a full decon, wash, Iron-X, clay, polish and Eraser wipe down prior to the Coating application.
I applied the coating in the advised cross-hatch pattern, applied in perhaps 20"x20" sections, insuring I over-lapped my application.
A minute or two the most after applying I came behind to wipe and level-smooth. One trick is do not wait too long to do this. Yes, some depends upon temperatures and perhaps even humidty levels. I was working at about 72-74F degrees that day in shade under my Carport.
I didn't notice what others have mentioned, "smeary", it laid down perfectly, and very smoothly. I insured I had good bright lighting, and as mentioned, do look at your work close up at various angles.
What I will say I noticed was not smeary, but a little bit "draggy" upon final leveling-smoothing, it is not as "slick' as I maybe thought it would've been. Still absolutely no issues of what could be referred to as smeary. It laid down like a sheet of glass upon the paint surface.
But instead of using MF Suede Sheets for final wipe, I used a couple of brand new Carpro Orange Boa MF Towels. They are extremely soft towels, and experienced absolutely no lint issues with these towels. (I believe I recall that I've even read Corey, the Carpro USA Distributor making mention of using the Boa Towels himself)
The end results were beyond my expectations.
Yes, Essence+ can be used, but IMO it won't be necessary to use this product for quite a length of time.
I would say a better and easier product to use to maintain the Coating, and its properties would be Carpro Reload.
In fact about a good hour after my CQ UK Coating was finished, I did come behind with Reload, to protect the coating during its full cure time, which is said to be about 7 days.
I should also note, that the Boa Towels were fine after, didn't turn into rocks because they were tossed in the wash immediately after using them
