I pretty much am resigned to porcelain damage to the bowls of any of my REDHEADS and do take precautions to use charcoal rings and baskets.
My preferred touch up paint of choice is only rated to 500*F and even with a 2000*F base primer, it will discolor.

The plastic handles are getting replaced with wood ones on the Chop-Top. I'll be playing around with a Pizza Que shortly on another RRR'd RED, so we'll see how that goes.
