My shameless commercial plug for this month is a new item. “D” whistles with holographic covered tubes. Here’s the link http://www.dbrooker.com/whistles.html - I’ll take the good opinions with the bad. And , YES, of course this makes them play better!
Interesting. They might be annoying outside on a sunny day, but they are kind of cool! 
I think they look cool–is the Feadog brass underneath? How well will the coating stay on?
Yes, both the Feadog and Acorn are brass - the “coating” is a special holographic vinyl film - take care of it as you would any other whistle and it’ll be there a long time. Thanks for the interest.
no offence, but the clear plastic ones are really ugly, my opinion only!
Being a crow at heart, I love shiny…
shiny shiny shiny
ooooo…
Looks like what that clown Michael Flatley did in “Lord of the Dance” with his little fairy girl/boy/who-knows character, and the two piece clare whistle he had. Cheesiest thing I’d ever seen was when the whistle was broken by whoever the bad guys were in his ridiculous act, and he comes prancing out all high and mighty (typical Flatley) and magicaly ‘fixes’ the whistle behind his back!
Well, anyway, that’s just what I was reminded of looking at the holographic wrapping. I think they’re kinda cool to look at, but I also think Flatley should have one shoved someplace unpleasant!

You could put the “rainbow foil” otherwise known as “diffraction grating foil” on a whistle if you want something that sparkles.
Edmund Scientific used to carry that stuff, but I haven’t seen one of their catalogs in ages.
FROSTED SHELLAC
A finish that I like to do on whistles is what I call “Frosted Shellac”. Shellac is a non-toxic finish and very durable.
Here is the procedure, do not try this on whistles with low melting points, remove the plastic head.
You’ll need Parks brand clear Shellac spray (I get it at Lowes)
Shake the can well before doing anything below.
First polish the whistle down to the brass with a high shine.
Second, put whistle tone body on a stick into a toaster over and heat for a couple of minutes.
Remove the whistle from the oven, carefull it’s hot (not responsible for burnt fingers)
(outdoors)
Before it starts cooling, spray the Shellac spray above the whistle so that the particles (overspray) falls on the whistle surface.
If it cools too quickly, you may have to repeat this. The second time is harder because you must be carefull to prevent the wet surface from contacting anything and avoid dust.
After the surface look appropriately frosted, put on a light direct coat of shellac to protect the frosting.
The postion of the can will affect the size of the shellac droplets depositing on the whistle from small to large, adjust this to your liking.
