No, you are not. I hate to see Lego models painted, especially when they are painted in colors that never existed. Plus spray paint just doesn't hold up as well as the original molded plastic. However, I must admit that I absolutely love the Chromed out wheels especially the darker colored chrome. I even own a few sets myself now . The original Black and Light Stone are just boring and horrid colors.
These dark colored chrome wheels look great and are not overdone or too gaudy.

I don't see an issue with the panels Paul painted as a temporary solution, but I would have just held off posting pictures of them. But I do remember him posting somewhere here that if he wouldn't have seen the new panels on the new sets that he wouldn't have done the model in black at all. I think he did the same thing with the long skinny panels in the Yellow Murcielago that he did. Someone also mentioned at Technicbricks that even designers at Lego paint parts before they are available to them.
