Best anodizing guide?

[JOGARA]

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...
