I foil my own lures with heat transfer foil. It works for paper as it is meant for printing, it works on wood and it works on plastic. One thing it doesn't work on is metal. It is not a coat of sticky glue, it is dry with a minimal amount of whatever adhesive which has to be heated to a very high temperature while having pressure put on it to press it to the surface.
When I wanted to do a mepps blade I had to put a thin layer of a special glue I have for work on the blade and then press the foil on and leave it to set before peeling the film off. It worked after a fashion but isn't great.
Another way might be to iron the foil onto some onto paper or if it can take the heat an address label and then stick that onto the metal and then seal with epoxy. I haven't tried that but it should work.
What you are after is holographic transfer foil, For the quantities you would be wanting the best way is to buy one meter at a time so you can get various types for not a lot of money to try different styles. Google "holographic nail foil" or "holographic nail transfer foil".
This is the one I have been using quite a bit recently
Is has a massive amount of coloured iridescence but is basically silver when no light is falling on it. Several lure companies use this pattern.
