Yah, probably right Larry. I have just always taped off the inside of the box after I purposely painted the inside of a Q100 lid and was told I did a big No-No. Plus, when I used to grind them out to a nice shiny finish, I didn't want some black paint taking away from it. I have noticed that there is "over spray" on most weber grills from the factory. I don't know if the different paint makes it OK for them to have some over spray but I agree that a little inside the cook box isn't a big deal.
