To the OP...be careful if you paint over rustoleum. I don't remember whether or not it is enamel but I do know that if you paint laquer over it you will have serious problems -- paint krinkle! Whatever paint you choose it would help to either stick with another Rustoleum product or make sure you are using another enamel based paint and test it on a small part of the cover's surface to see if it is compatible.
Before you paint them, not only lightly sand them down -- or scotch brite them -- but lay a thin coat of primer down and let that dry thouroughly, and when you paint them use VERY thin coats and wait 15 minutes between coats too until you get the look you want.
I don't recommend removing any paint as the original paint is going to be the best adhesive you can get on the plastic.
