Odorless Painting Options for PLA Parts

[radian]

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.
