Thanks, everyone. I should make more progress today.
The basic difference that I see between the new AK-INTERACTIVE chipping liquids and hairspray are very good:
Not sticky, not smelly, it goes on smooth and it has consistent and reliable results with water. It's an acrylic product, and the results are again more trust-worthy. The price is also a factor, although you do get a smaller amount.
I am still working on the comparison between the "Worn Effects" and the "Heavy Chipping".
The new products are going to be discussed at length in Mig Jimenez's new F.A.Q. book which is coming out shortly.
