sorry that made me chuckle as i know how you feel when talking about the heat and having to be anywhere near the oven or in it,which not good.we spray so many items.we use a convey system with pretreatment at 55c,dry oven at 160C,cure oven 180,190c.The paint process in all takes about 2 and a half hours.We use different speed settings for different paints and depending on size of the item.The quickest cure we can do is Ten to 15Mins but on rare occasions.
