powdercoating theory

I have some "Cold Gal" paint....really expensive stuff....and it is damn heavy.....has lots of metals in it.
I have used spray pack paint (engine enamel) to paint brackets and things ( really laid it on), then baked it in my oven at about 110-120*F for about an hour, hour and a half, and it comes out looking like powder coating.
I use VHT branded paint for that.
