[Phono-L] Advice please - holes in cylinder surface

Chris, These holes look indeed different than the ones I used to find 
sometimes on black wax cylinders. The usual holes are, to what I was to 
figure out, caused by the collapse of the wax surface when tiny bubbles 
are underneath it. You can see this sometimes on broken black wax 
cylinders, both 2-minute and 4-minutes.
The holes on your cylinder do not have an uncommon size though. It's 
just the large group of them what looks suspicious. A regular stylus 
should even be able to play over such an area, especially when you are 
using a Model B reproducer which has a bullet sapphire instead of the 
doorknob of a C.
As Steven pointed out, candle wax could actually do but it can be sticky 
and, as a worst case, can mess up your stylus that has to cleaned then. 
I had good success with filling comparable holes with modelling wax (for 
wood restoration) with a wooden toothpick. It takes a lot of time and 
you should have the cylinder on the mandrel to give it a better support 
while applying the wax.
