WHY?

Those are things for fans of restoration
(Here in Italy there are many fans of old radio that prefer to have the old radio looking as original)

or

for people who want to sell something of vintage as untouched and original

as to get more money from collectors

I have yet to spend the money to destroy some caps and prove it, but I suspect a similar process turns new caps into Jupiter cap products like this (http://jupitercondenser.com/vintage-tone-red-capacitors.html).

They tell you the long/skinny caps are mylar (polyester). Those could easily be M150's (or any comparable part) with a new wax casing and label, after the technique shown in the original post.

May be you can discover something also without to destroy a cap

if you have access to a XRAY station

may be your dentist can help you on this thing

I'll confess that I did something very similar once.

here's how it happened: I took some dress pants off a dry cleaners hanger.. the pants type, with the cardboard tube.  I noticed the tube was about the diameter of some old caps.... so I put the hanger on my workbench.  the next weekend,  I fooled around with it a bit,  cut it with a sharp knife,  put some cheap xicon lytic cap in it,  and dripped candle wax into it,, just like this DIYer did!

To be honest, I couldn't bring myself to put the cap in the amp...  to me, it was too much hokey-ness. and ,, on top of that,,  I knew there was a cheap xicon in there!!!

I'll add a tip for the guys that are serious about it,,,.  use a nice yankee candle wax,, like pine-mountain or pumpkin-something, so when your amp heats up, and that wax begins to ooze, your bandmates will all be subtly charmed.

In other words, people who want to commit fraud.  I don't approve of that.  But as I said, I do understand.
