I'm about to vanish an acrylic painting I've been working on but there is some oily finger marks on it. i don't know much about preservation of paintings besides the minimal related topics linked to my graphic communications major, so I've varnished a couple dozen times but not enough to run into this problem when it comes to professional work.
I bought Liquitex Professional varnish spray in matte, Will it get rid of the marks? do i have to clean/repaint parts before varnishing? videos/articles would be much appreciated.
also share some art and stories/struggles if you like
