You may try a few Thin layers of shellac and then the VHT. If I remember right that is the process Torges recommended over skins. The only issue I have with tru oil is that it darkens/yellows. However it does make the color of the skins pop.
I just checked the VHT and it is flexable, and I like the way Shellac dries fast for finding scratches and filling the grain.
Bvas--I had a piece of flat glass, and one day as I was spraying round up with the pump up sprayer, I was thinking about orange peel, after I washed it out I laid the glass on the floor a sprayed some water on it , it beaded up, so I sprayed some more on it, after I sprayed enough water on, it all came together and flattened out.
I think we are not laying down enough to flatten out
