I have read somewhere that you do not want to heat a part to rapidly when you are curing it. They said it needs time to flow out completly before it reaches cure temp. How long should that be? I pull out part hot and set oven temp to 450. Apply second coat and put back in oven for approx. 6 min. The part is at 400 so i turn down oven temp and keep the part at 400. Is this ok? Any help would be great. Thanks!!
