Seeking advice on applying clear powder coat

Everybody is a beginner at some time. About 20 years ago, I bought a $99 Eastwood powder coating gun, and the rest is history. I have never used the Cerakote, but I know a professional powder coater who uses it all the time. Let me suggest one thing. It is rather labor intensive and will take a while, but it is something you can do with basic equipment. Did you know you can polish cured powder like paint? Try this. Put two coats of clear on one of those parts, wet sand it with 1500 grit sandpaper followed by 2000 grit, and then polish the parts by hand with a microfiber towel. Will it be a pain? Yes. Will it work and give you a like glass shine? Yes. I have done it a few times, and it does work.
On your second coat, you can try one of two things (FIRST, make sure you have a GOOD ground):
1. Using your laser thermometer (I assume you have one) let the part with the first coat cool down to about 160 degrees and then spray on the second coat. Powder will stick better on a warm part.
2. Try hot flocking the second coat. Hot flocking is spraying the powder on to a part right out of the oven when it is 375 degrees (or whatever you use). The powder hits the part, instantly sticks and instantly melts and flows out. Then you put it right back into the oven to cure it. It works very well, but you have to be careful. It is really easy to get the powder too thick; thick enough to actually run and drip. However, if you are careful, it can work for you.
