I usually spray only a few light layers of acrylic paint on the stators. The paint is so thin that it doesn't reduce the open area, IMO.
Ah right, well I plan to put a moisture protector (or whatever it is called) between the ear and the driver but guess dust can get in to the backside that is not covered. On the moisture protector, I was thinking of using some EPDM self adhesive foam and mount the 2um mylar to that, taught but not especially tight, I am thinking this might be quite good (if I can get it stablise and not just collapse when it is in place) as the slight amount of flex in the EPDM will seal the driver in nicely to the head and will allow the mylar to move a little thus reducing any colouration, what do you think?
Sorry another one while I think about it, I have some anti static wipes (computer monitor ones) that I was going to give a go on the mylar, an idea if these will be ok? I guess I am looking to get a resistance across the sheet of a few mega ohms? Do you find a difference in using the gel rather than just the soaked wipes?
