Ok everyone, here is the summary of my testing today.
Background: I applied 4 marker lines (same blue sharpie as before) to the top of my dryer (same dryer used in previous tests). I cleaning the top of the dryer with Denatured alcohol to ensure nothing was on the surface to prevent contamination.
The lines are as follows: (from left to right in pic)
Line 1: A control sample. Marker with nothing applied over it.
Line 2: Marker with 1 layer of Z2 (w/ZFX) applied over it.
Line 3: Marker with 2 layers of Z2 (w/ZFX) applied over it
Line 4: Marker with 3 layers of Z2 (w/ZFX) applied over it.
Each layer of Zaino was allowed to dry for a FULL HOUR before being removed with a microfiber towel. I followed the instructions supplied by Zaino Bros for the proper mixing of Z2 with ZFX. The Z2/ZFX mix was applied to the entire length of the line. NXT was applied through the center of each of these lines. The Z2/ZFX combo didn't lift any of the marker.
Here is a picture of all 4 lines, post Zaino application, just prior to NXT application.
NXT was applied in the same method as my previous test. A small drop (little bigger than a dime) on a foam applicator and worked back and fourth for 5 strokes with medium pressure.
Control sample - NXT had no problem removing the control sample with no product applied over it. Given my previous test, this is not suprising, so lets move on. ļ
1 layer of Z2 (w/ZFX) As you can see from the picture below, NXT removed the marker, even with 1 layer of Z2 on it.
2 layers of Z2 (w/ZFX) This is where the test began to get more interesting. After applying NXT to this line, it removed a portion of the marker. It didn't, however, remove as much as it did with only 1 layer. The center portion of the application area was removed first and there blurring of the line that extends out from the center. While removal was less, it still removed some of the marker. Please refer to the picture below, each line is marked.
3 layers of Z2 (w/ZFX)- After NXT application on this line, once again some of the marker was removed. This line, was the least however. The spot were it was totally removed is smaller than the line with 2 layers of Z2, but the area of blurring (partial removal) that extends out from the center is greater. Please refer to the picture above.
Here is picture after the application of NXT to all the lines, with their respective applicator pads above each labeled line.
Conclusion I'm sad to report that NXT removed a least a portion of the marker line in each scenario. It did remove less and less as the number of Zaino layers on top of the line got higher. Well, there you have it! Make of it what you will.
