Thanks slash that is very helpful, much appreciated I now know what I am dealing with..
Yeah so far so good, each one is going to have a different surface now so it will be interesting to see and feel the difference plus the durability and longevity.
First one was Crystal Clear Acrylic in a spray can, second was Polyurethane and third will be KBS so I will be able to compare which was best to work with also..
Once done I will put up a post on what I found with each etc..
As for the areas you came across that it wasn't adhering what did you use for a prep?
I use Repco Wax & Grease Remover (Prepare) and it seems to work really well, I had one spot on the Sinbad that I tested wax polish on then cleaned it with the Repco gear then tried another coat of Poly and it did not adhere on that area, it did what you said happened to you so I sanded the area again then used the prep and all good. So a good even sanding and the repco stuff will give you a great surface to clear coat.
Thanks again for your help.
