A very good product !

Okay, after many years in the Construction Industry both as A Contractor and A Superintendent on Commercial projects, I have supervised the use and clean up of almost every type of paint out there, This is A different animal to me the preparation and the application I find is very important, most importantly prep the surfaces, sounds wild but I used Dove Detergent, the one thing this stuff won't stick to is oil or grease, the next most important thing is to clean this off your hands I found (2) things that really worked, (1) A Product called “Goof Off” ( or something like that) The other is “ Lighter Fluid” I tried to recoat after the product dried, it pealed off, I am getting ready to try to take A Clean cloth with Lighter Fluid on it and try to Tack Out the Surface if I can then I will be able to re-coat the surface ? I will let you know in A future Evaluation, ☝️
