About the powder coating
Where I buy it I am sorry but I won't share that info, will never risk losing my access to that supplier.
Then further, you have to buy in quantities that you would not be able to use up even if you made bucktails commercially.
I had to buy that way, that's how they sell it.
I am however prepared to share some of my powder with fellow lure anglers, by supplying it in smaller quantities if there is interest.
Note that this is not a commercial venture, I will help others while I recover some of the money I had to spend on buying the stuff and having it couriered to me.
If you are interested let me know, will check plastics warehouse to see the size of the containers.
Keep in mind that there will be courier costs aswell, maybe something like postnet will work out cheapest - counter to counter
As for the "bucktail", well it's not really bucktail, it's a synthetic type of material that's much cheaper than bucktail, I get it from the local tackle shops
