That is some very interesting advice. I never really thought of doing that.I did this on my Gen 3 (so its a little different), but it works better if you mask the perimeter off with fine line tape, then use blue masking tape to fill (overlapping the fine line tape). The fine line tape seals against the plastic better, gives a hard edge and doesn't tend to wick paint under it that easily. It is sort of an art to making it conform to curves (you have to stretch it just right), but it's cheap enough you can just keep trying until you have it. Use one continuous piece for each section and really line up the overlap.
Then just use tons of light coats of paint. Never actually lay down a full coat. Mist and dry, mist and dry.
