I have used the
Nanoskin Autoscrub Towel – Fine Grade for years with good results. I have not seen any micro marring from the
FINE GRADE.
I had a 2010 White Ford F150 recently that was "covered" in grey paint overspray from painters spray painting the house next door to his.
For that I used the
Nanoskin Autoscrub Fine Foam Pad – 6 inch on a PC 7424xp and it made short work of removing 95% of the overspray.
There were a "few" areas and curves that I followed up with a traditional clay bar in order to remove overspray in the small curvy areas.
When my current towel "wears out" my next purchase will be a
Nanoskin AutoScrub Fine Grade Wash Mitt instead of a towel. Why you ask?
I fold the towel into 4 sections (like I do microfiber towels) and if the polymerized rubber is not wet with clay lube the rubber sticks together.
A mitt is one sided, I can put my hand inside and should easily be able to decon the worst of the contaminants with the one side of the mitt.
The advantage of the towel is that I have 8 clean sides (although much smaller) to work from and I can continue without constant rinsing.
Now is a mitt "better" than a traditional clay bar? I`ve found that on "most" vehicles (after Iron-X and a thorough rinse) the Autoscrub works fine.
Even if (after the baggie test) I still find a few specks left behind, I then use traditional clay to refine the surface for any "orphaned" contaminants.
Short version: The Autoscrub works 90% of the time. If traditional clay is needed for a follow up, the clay bar is MUCH cleaner when you are done.
I can do 50+ vehicles with an Autoscrub. If you drop Autoscrub on the ground you can rinse it off. I`m lucky if I get 4-5 vehicles out of a clay bar.
IMHO the (Autoscrub FINE GRADE) is a worthwhile investment. It makes your quality clay bars stay cleaner and they last much longer.
