I've used the FP stands for years now and really haven't had any issues. Have had the odd rubber end cap stick to the surface of the Valkyrie but no paint ever got damaged or discoloured. I know other people have had issues but I have always made an effort to keep my Valks displayed in a cooler or more controlled climate. Maybe high heat would cause them to react with what ever surface they are supporting but as I said I haven't had the problem. I still have Valks on them now and they aren't new stands either.
