Well indeed traditional wood grain filling is really the time when 95 kilos of muscle helps
ah ah ah : )
Please look at the photo, and tell me which one is the intruder according to you,
from left to right, we have wax, two ethanol based varnish, one water based varnish,
then a nitrocellulose based varnish (the Tamiya spray).
We could think that the intruder is the Tamiya spray but for me there is in fact no intruder.
Historically speaking, the nitrocellulose varnish started to be used in cabinestry around 1920, almost 100 years ago (« Bois:guide des finitions » page 48/ « Les secrets du vernissage » page 14) so it is not a anachronism to use it nowadays for example on the Art Déco furniture.
Now technically speaking, even if the components are not as natural as the « pure » traditional ethanol based varnishes, it is still working on the resin/solvent system (like ethanol based varnishes) which means that the shiny layer remains after the solvent evaporated. So even on the technical side it is crosser to the traditional finishing than the modern ones.
The only refraining point I could see, indeed not see, is what is inside the varnish. Actually it seems difficult to know exactly what are the components.
Personally I never used it yet, I will make some few tests and then see.
I just would like to show this item, how it was,
It is a walnut tea table, we call it « Table à thé ».
I am showing you the stains that were there and there:
And then it became like this after it went to my workshop.
To make it clean I did not use sand paper at all.
So the good point is the patina is 100 pour cent preserved, but the flip side of the coin is
that at some point some stains are very slightly remaining.
Anyway the table is nice.
I finally could make a maintenance to the Gothic cabinet I had and I put it back online,
you can see it here :
