Very good question. In my experience, the corrosion issue with regard to masked off areas has never been a factor. Yes, it will corrode, but the teeth will cut through that. The masking off of areas has also been internal to the product. Yes, I've also used the star washers on painted areas (non-conductive paint at that) without a problem, but my *preference* is masked off areas.
If you're subjecting your product to some extremes in environment other than normal office environment, then corrosion will most definitely be a concern. If you're going to use star washers on surfaces painted with non-conductive paint, then you may want to consider using a torque wrench for securing the nuts or bolts during assembly.
