Try Parafilm M which is available many places on the internet. It's a laboratory masking material that works great on plastic bodies. It comes on a roll and has a backing film that removes very easily. You then stretch the film to approximately 150% of it's original size. Then let it shrink back for about 30 seconds and apply to the area you want to mask. Press down but be careful not to "nick" the applied film, a finger works well for this. The film will easily stretch to accommodate compound curves with ease and even if you get a few folds in it it will still seal against paint intrusion. The last thing is to cut the film with an x-acto knife and press the edges gently with a finger. You will get incredibly sharp lines with virtually no paint intrusion. It does take a little bit of trail and error to get the feel of it but once you do you'll probably never use tape again.
