Nice replies guys
A bit of contextual info:
although I'm not hung up on insect secretions, bleached shellac is absolutely my favourite finishing medium for our drums. It's way more work than any spray application, but worth it in terms of featuring the wood rather than featuring the "finish".
This is the application of the scratch / sealing coat. It's quickly applied, although it still needs to be even. once dry, it's sanded back down to near bare wood, then we build up layers from that foundation, sanding between each layer.
The applicator is called a rubber (calm down American types
. It's a lint free cloth filled with shredded cotton waste. You "feed" the rubber by adding shellac to the filling, not by dipping it into the shellac. Essentially, you control the flow of shellac by squeezing it / applying pressure. In later applications, different motions are used to get an even effect, although the wood type often dictates that. For example, zebrano dictates all vertical strokes, whereas this segmented shell benefits from multi directional application.
The reason for posting this was to offer a little insight, but also to share the joy of the first "reveal" = always special. The iridescence of this species & construction under changing light blows me away every time
