Might be tempted to try it out at some point, easier than messing around with large amounts of acid solution... just need to build an oven big enough for the larger parts but that's easy enough to DIY I would think.
So after 18 cases + a few test parts I have used the whole 1/2 KG bag with the following remaining;

The bottle on the left is the fresh powder that I have left to use the one of the right is 90% of the powder that did not stick.
There was quite a layer at the bottom of my professional spray booth (which is definitely not the oven box on its side..)
Did have a couple odd spots on some of the early attempts. Not sure what went wrong here. Only happened on a few faces. Looks like it could be gas escaping from the part or clumps from storage, but only happens on certain faces of the part...?

PS, buy a face mask. I forgot till after I was spraying all day and I can feel it.
Probably wont do that much damage compared to the crap we use to thrown on the bonfire when I was a kid...
