Oh you got a suit from Kris.. That's a great suit. What everyone said here is correct. You should just plastidip it if you feel it requires a paint job.
I would suggest though. since you have a very nice suit and cowl that you wait before you start buying supplies.. you may not even have to plastidip it.
If you're planning on wearing the suit you need to get a decent undersuit.. You could get a typical wetsuit.. or you can go really high end and get a undersuit specifically made for the begins suit from "Davidyr1" He can be found on brotherhood of the bat. I'm a member there too.
Rubberhood of the bat has some tutorials, less users, but is a good resource as well. In fact a post just went up as to how to paint latex. You might want to check it out. These instructions are much more complicated than a simple plastidip job. If you're up to it, I would recommend doing it the more complicated way. If you're planning on wearing it, plastidip is good and flexible, but eventually it does crack, especailly if the suit is worn.
enjoy your suit!
