I had the same problem with the version 2 tips reacting with the paint. This happened when I put my V2 1/60 Super VF-1A Hikaru on it. At that time I thought it was because the paint job wasn't exactly cured complete and the pressure on the silicone caused it to liquefy somewhat. Seeing the posts now, maybe not, but rather the tips reacting with teh paint.
Anyway, since have placed the tips on non painted parts and so far so good.
