SG does have cleaning ability

I started a personal test today involving bill north vs. 24 hour waiting before buffing method.



Upon removing SG using the bill north method some of the sharpie marker I used was removed. I repeated the experiment 3x and found the same result. The amount removed was equal to how much a 5:1 APC dillution removed or even dawn wash :o



The amount removed did not hinder the appearance of the market on the washer surface whatsoever, it looked entirely intact. However it did show up on the MF towel I buffed the SG off the panel with.



I also tried water and the towel on a separate area, it took nothing off.



I tried s100 and a MF towel o na separate area, it took nothing off.



This leaves me to believe that SG has cleaners or somehow can slightly clean.
 
I had a real life situation where I had to remove permanent marks from the rear bumper of a Porsche, AIO by hand alone didn't touch it :eek: It removed easily with the PC though :up



Here are the marks:

this morning I went ahead and did the next coat for my experiment, once again it took the same amount of sharpie off upon application to the panels. When I buffed off the panels with the dried SG from the previous day it took nothing off, however merely spreading the new SG on the panels took sharpie off.



Just sharing my experience.
 
Sounds like the solvent is what is cleaning the marker, as evidenced by the dried SG not removing anything - the solvents had completely evaporated, thus no cleaning ability.

some updates.



the sections are sectioned off with painter's masking tape. i lifted the tape a little today just to look at the thickness. the SG and s100 are clearly quite thickly coating!!! noticably to the touch.. the s100 is about twice as thick as the SG with 3 coats on each.
 
oo also the bill north and normally applied SG sections both are teh same thickness after 3 coats. the Billnorth method without question works... there is a visible layer of bonded SG when i pull the tape up to expose untouched area.

This is interesting as well. But this contradicts the findings in your first post. I wonder how this can be explained?

If SG has cleaners using WOO, we're assuming that it is cleaning itself (previous layers) off the paint. But now you are saying that both methods are leaving the same amount of SG on the paint.

I think what BillNorth is saying is that if you "repeated the experiment 3x" *in the same spot*, and got marker ink each time, then there wasn't any remaining/layered SG protecting the marker- it'd been cleaned off each time. That's how you got down to marker each time. And that's why it shouldn't have been as "thickly layered".



If you repeated it in three different places, well, that's different.
 
Bill, your method and the normal method act one in the same, both remove marker when I add a layer. Both methods are equally thick in visible thickness versus under the tape that divides them.
 
*Confused*



Ok so what you're saying is that when you apply the 2x or 3x coat, you're getting marker residue on your application pad? or your buffing pad?



And if so... Then by your method the first layer of SG could not have been intact to be built upon if you are still picking up marker residue on the 2x and 3x passes... Maybe the SG picks up some of the marker; leaves it on the top of the layer... Hell thats weird. :nixweiss
