Well, I've run out of donor bodies to experiment on, so we're diving straight in with my full-body repaint.
This go 'round the method lineup is as follows: sanding, wipe down with acetone, panic upon noticing the acetone is eating through part of the plastic and immerse in water, sand off acetone-shiny spots and smooth eaten spots the next day, and we're going with a light dusting of primer, followed by a once-over with white paint pens around the joints, then a few very light coats of Krylon. We'll see how that goes.
My budget is not allowing for more $10/can spray paint, or I'd have nabbed a can of the paint for vinyl/plastic from the auto parts store. (Woe!)
Meanwhile, Nii is playing dress-up with my existing MH wardrobe. She is very disappointed in the lack of purple choices, but she's soldiering on regardless.
Nii, that is NOT what I had in mind when I purchased that desk.
