Quoted from Vintage-Pinball:I forgot to add that 2k products gave a "pot life" of some 20 minutes on average, dependent on the air temps and if you use a fast or slow activator so dont mix it up until you are ready to apply it or you will get an awful cleaning job to do on your spray gun!
I don't know what brand of clear you are using but most activated clear coats have a longer pot life. Usually most automotive clear coats have a pot life around 1.5-3 hours. Do you mean 'flash times'? The flash time of most clears are 5-15 minutes. You need to really look at the TDS sheet of the clear coat you are using. I use DC5335 and the pot life is 1.5-2 hours. The flash time is 5-10 min.
