Odorless Painting Options for PLA Parts

Hi. So PLA seems to come is all types of colors, but do the hassle of switching filaments back and forth, I'm playing with the idea of just buying the natural-colored stuff and painting it to whatever color I like. I'd like to go odorless as I don't have a workspace, so where I will be painting is where I will be eating (literally, my apartment is one big space and I only have one table). It's also -25 C out, so I can't exactly open a window.

Does anyone have any experience painting with odorless acrylic? The goal is to have an even finish that does not rub off. Would adding a primer help at all? I will be lightly sanding to create a better surface for painting.

Thanks

A Matte primer is essential otherwise it won't stick to PLA very well. ABS is a bit better but primer is always the safer bet, this also fills in the print lines somewhat and covers any mess.
