Second coat question

[hurricaneracing]

OK new pcer here. I have powdered some parts that didnt turn out as "deep in color " as I wanted so tried to put on a second coat. The powder seemed not to want to stick on the whole part. At one point it looked like it had chicken poks or something with the powder only sticking in small round spots. Should I sand between coats? I have both caswell guns and both seem the same no matter where the voltage is.

sand with 220. then i preheat and let cool to around 120 to 150. this seem to help the powder to stick. hope this helps

Yes sir shot the second or top coats hot......... and after you see how good that works I bet you start shooting everything hot. That’s what happened to me now I run the part through one heat cycle and take it out and used to wait until it dropped to 150 but now I wait just long enough to get the powder in the cup and get the ground on and start to shot. But watch you can put too much on. But man does it work great and look on the floor there's no waste.

See my thread: faraday?

Do you cure it at the same temperature and same amount of time?
I'm having trouble with the second coat becoming orange peel, the first thin coat looks 100 times better than my second or third.
