Some good ideas, Tower ARFs use Mono and Horizon use Ultra {most the time} They can still be a different brand or type of covering but that is a basic overview. Other ARFs?? I have seen covering that I have used in my shelves with stick on backing.
I start with a hot covering iron and often finish with a heat gun depending on how the covering reacts. Some covering doesn't like to shrink again so I leave it alone, just the nature of the beast. A hole in the bubbles with a very small, sharp pin works wonders, it gives the air/gas a place to escape.
