I did this two weeks ago, and it looked great at first. Skis were already mounted, so I left them on, but taped them off completely with plastic bags and blue painters tape (after sanding). Started by sanding with about 300 grit sand paper and eventually moved to 400 and then 600. Cleaned them off with a wet rag and let them dry before I hit them with the first coat. The spray paint I used was just a matte black can supposedly ok with metals, plastics, and woods. After two coats, the skis looked really good, but I went back with two coats of matte clear. Despite being super clean, the paint chips really easily. I think automotive paint with a sprayer would really be the way to go for durability.
ive used krylon fusion, which is a paint for plastic, and gotten good results. one can will give you 5 or 6 thin coats. and its only like 3.50 at walmart. i got all last season on the first paint job. it scratched up some, but not terrible. and then over the summer, i sanded the skis down and went with a different look. 26 days in, and they still look good.
