I just had a major malfunction trying to put "tintable" Monstaline on my roof. I picked up $84 worth of Cygnus White "tint" and mixed it right in! s*** looked good for all of 10 min before it became oatmeal. I really think the paint shop sold me the wrong stuff. I called another paint shop and got a lot of confusion about how they could sell me the paint but not the "tint". It didnt really make sense. But also i dont know what i am doing. Does anyone know of any paint shops that are familiar with tinting Monstaline?
