Depending on the sharpie used, even water could remove some of the sharpie mark but would we really consider water to have the kind of cleaning ability that we associate with car care products? (Of course water cleans, but I am referring to a more vigorous cleaning property) In addition, the mechanical rubbing of products over the sharpie mark will create friction and possibly remove some marks. Lastly, it may just be chance that the solvent used in a product happen to be able to dissolve the sharpie mark (the ink is carried also in an organic solvent-the odour is the smell from a volatile organic solvent and that's why sharpie marks dry so fast) yet the solvent in the product will not be able to tackle impurities that we find on car finishes. |
I think the one thing you are totally missing in all of this is that SRL's test was performed in a controlled consistent environment. He used the same sharpie on the same washing machine with the same detailing products as well as water. His results do provide a great deal of insight into the cleaning properties of the products tested. Regardless of whether or not he was removing sharpie or clearcoat the fact remains that NXT was the only one that actually removed something, while z, k, and water did not. Now this may not necessarily mean that NXT is harsh, but IT DOES give a good indication that Z and K are very gentle, more so than NXT.
The part of the test that I found to be even more compelling was when NXT removed the sharpie that was COVERED by the z2/zfx combo. I think this definitively tells us that NXT will in fact remove other sealants when attempting to layer over top. And that was really the big question on everyones mind.
JMHO,
