I have a question/concern I’d like everyone’s input on. I’ve sprayed 3 colors now on my wings. All ranthane. Blue, yellow and black. Every time I inevitably catalyzed more paint then required so up till now The next day I was left with a bucket of hard paint. Basically a rubber color brick. That was the case with both yellow and blue. Now I sprayed black about two days ago and did everything the same. Sprayed the wing and the coat went on well and looks great and is hard (seeming) to the touch. But... the bucket of remaining black paint is still fully liquid. How could this be? Should I be concerned the paint on the wing isn’t cured? The bucket and Wong were in the same room for the whole process. Any thoughts?
