Product separates when using with expoxy one coat. Also, the foam deteriorates quickly leaving bits of foam in the paint, as well as separates from the plastic core. DON'T USE THIS PRODUCT

Used to apply two-part epoxy primer and two-part polyurethane paint on aluminum mast, boom, spin pole. Foam covering separates from fiber core. To cover half the circumferance of my 66 foot mast would require 5 covers. Initially I cut the roller covers in half (3.5 inches) when rolling my boom. I thought this may have caused the problem. However, I got the same failure using a full size (uncut) roller cover on my mast. I switched to another brand of foam roller cover and was able to complete one full coat on my mast using only one roller cover. It's possible the curvature of the mast caused the foam covering to creep on the core and that this failure would not occur on large flat surfaces.
