Yes...Renaissance Wax Polish
This product manufacturer claimed it is used by the British Museum
so I called the BM to check. I enjoyed my inquiry
being treated with great respect by a gentleman in the
restoration department. I was informed they
do indeed use it and they find it truly
is a wonderful product. Absolutely safe to use as a
protective coat on paintings.
Get this...it dries almost instantly
and it has not lifted off any color.
I placed my painting done on Yupo paper
in water overnight after coating, and it
remained perfectly protected so it really is excellent as a sealer.
As well as waxing the Yupo paper,
I have tried it on a watercolor painted on aquabord,
a gouache painting done on 100% cotton paper,
and I liked the finish it gives, very much.
It smells like furniture polish before it dries so I use it in a vented area.
Below is a very short video showing how I apply it.
(unedited as I do not know how to do that yet)
I place it on with a palette knife using the bottom flat part to spread.
An old cotton t-shirt is perfect to buff it up to the sheen I like.
A note about price.
I purchased mine at the Artisan in Santa Fe NM.
The 200ml size was $35.50. Not cheap!
It goes a long way and this may last me a lifetime!
I do like Gamblin's Cold Wax for mixing with oil paint. This is not to be confused
with that type of use.
