Specified cure temp 390, started to flow at about 225, where do you start your time at? At what point will clear start to yellow or cloud up?
Start your your clock when the part reaches cure temp. If you follow the powder manufacturers cure times and temps you should n't have to worry about yellowing, that's from being overcured.
