Has anyone tried applying some kind of doping to their LE5-2 midrange?

I did the center caps on my L123A woofers as part of my L100 restoration (http://www.audioheritage.org/vbulletin/showthread.php?30368-Newbie-JBL-L100-restoration-and-upgrade) project and they look really good IMHO. I used the "wet look" paint from Parts Express.

Just wondering if it would have any negative effects on the sound, the LE25 tweeter I did out of necessity (had to pull the dome out) doesn't sound any different.

Back in the day, I used to use real cellulose dope, the stuff you'd put on model airplanes. It's probably illegal now, like most of the good chemicals, it used to stink the place out.
