Need to find a specific type of lacquer, info and illustration inside

First of all, I'm not a native english speaker and I don't discuss these things very often, so sorry for any mistakes and if there's something unclear, please ask.

I want to learn to do kintsugi, a japanese method of repairing broken ceramics that uses ground metals like gold or silver to decorate the repaired places - it can look for example like this. However, I want to use modern polymers instead of traditional lacquers, because they're expensive as hell, bad for your skin and I really see no reason to use them as long as I'm only doing the kintsugi for myself.

This method uses 3 kinds of lacquers, I know how to substitute 2 of them (I'll try various epoxy glues or superglues, possibly with some filling), but for the last one I have no idea.

Where is it needed/what attributes does it need to have? After gluing two pieces together, you put another superthin layer of glue along the glued crack and sprinkle it with fine metal dust. After it dries, you knock off the dust that didn't stick and you apply the lacquer - this is the one I need. Here is a simple illustration that might help. It should also be food-safe after it dries for obvious reasons, but that's not a deal-breaker.

The problem is - the final layer must be very very thin and it should spread out by itself a bit, because it's impossible to evenly apply it over the whole area of the crack without sloppily putting it on the surrounding areas too. The natural japanese lacquer is applied mostly by putting tiny dabs every few milimeters of the crack, spreading it out just a little bit with a very small brush, waiting a little bit so that it spreads all over the metal dust by itself and then wiping the excess off. After it dries, it can be polished. This is the behavior I'm looking for, but in some lacquer that's cheaper and can be bought in Europe or USA. I have no idea what to look for or where to ask, so if you have some tips where to go next, I appreciate those too.
