That’s because he’s so good. When people hear me playing my brass SessionPro, they say “That Mike Burke is really amazing!” 
Anyway, Mike, if it wasn’t for you peddling a couple of your whistles to me in St Louis a couple of years ago, i wouldn’t even be whistling today. Thanks!
Hey, contact me in private and then I can tell you ALL about myself! 
Araldite brand has an aluminium powder-filled epoxy, so does Loctite (and I guess many others). This stuff is amazing. Once cured you can file it, or even thread it.
In motorcycle endurance races, we (and major teams, too) used it to repair aluminium engine cases spilling oil after a fall on a track. We’d paste that sloppily directly over the hot engine (just using solvent to remove the oil from the surface)!
The only problem is that even polished it doesn’t look like aluminium, but more like lead.
Mike and Ronaldo thanks for the input.
I feel less “bored and perturbed” with this topic all the time. 
Mostly thanks for the great contributions to whistledom in general. Your instruments have brought me and my family great joy.
