Cool - glad you got it, I've been meaning to ask you about him.
You definitely want to do the boil & pop method on Data, as wave 3 wasn't produced in the best quality. When the Data came out, some people tried to pry his arm off without the method and ended up breaking the joint. All of those that used boil & pop were fine, though. On TrekToy there are numerous people that frequently do the boil & pop method on DST figures and all of them mention there is no effect whatsoever to the paint. The only risk is if you forget that you're not supposed to stick your hand in the boiling water.
