The varnish that I use is not the same as the varnish that I use when painting on canvas, It would not be durable enough to withstand the sanding under water procedure. I use a varnish that is composed of polyurethane. I have tried many brands, but the one I find most durable and leaves an almost “rock hard” finish is a product called Varathane. This product will give the art a Photo-Realism finish. This varnishing technique can only be on board only! When purchasing this varnish make sure it is Semi-Gloss . Trompe L’ oeil is a method of painting that fools the eye, my method of varnishing which is called “crystal-blend” enhances the art even more to produce the photo-realism effect.

Could you share the purpose of varnishing?

Wonderful painting by the way, I really love the way you approach your work.
