As have completed a many of murals in latex and acrylic.....I have always used the Flecto brand Diamond Coat comes in a satin, semi-gloss and high gloss. The satin works well, Clorox is a no- no I feel for any artwork. But having put a finish in a high volume kitchen in a hotel above the grease pit......several coats of this varnish seemed to work well. I have also used this over canvas, wood, metal and wall surfaces. I really like this clear-coat, as water based materials go. Hope this helps.
