I was using a yellow wood varnish which is readily available in hardware stores to seal my acrylic painting. They are cheap and good varnishes, but the problem with them is that they leave a yellowish shine which changes the original color of my painting. And the yellowish shine increases with time.
Now I am in search of an alternative which is equally good and cheap. I also don't want to spend much on the varnish.
Can anyone suggest a varnish I could use?
