Ghostbond update. I very, very methodically put on a piece using Ghostbond Platinum w/ 2-3 layers depending on placement. I don't just paint my head & stick it on.
I position the piece on my head & secure the center, to anchor it. Then I do the rest.
I did use scalp protector, but only Walker's weakest variety, in spray form. I don't know how much it does because when I sprayed it on my arm before using it on my head, I went to bed & when I woke up, I did see any translucent film where I had sprayed it.
For comparison, when I use the Thick form, I absolutely see a film on my arm, foot, wherever I apply it, for days afterward.
This application literally took an hour & was very methodical.
