It's always challenging coming up with titles for abstracts but I like the idea of using "Transit of Venus" for this one.
From the book "New Acrylics Essentials Sourcebook:
"When re-priming surfaces, use proper ground, never wall pant. An artist acrylic gesso is designed to be compatible with flexible and rigid substrates. ...A wall paint is designed for a flat, rigid surface and does not carry enough binder and thus will not adhere as permanently to the support, nor will it be flexible enough to weather any structural changes; this type of primer will crack and or flake off and will ultimately have a negative effect on the permanence and structural integrity of the entire piece."
I used to prime my hardboards with just latex paint. On one painting, as I was adding layers, the layers below began to disintegrate and pull off. Lesson learned. Invest in gesso and use it. If you want really smooth canvases or boards, use several thin coats of gesso, sanding (when dry) between coats.
