I will just toss in this observation: I recently bought my first new Weber kettle in years. It is a crimson (now discontinued) that I got from BBQGuys.com on a "scratch and dent" sale. I like the color, but, man, when you compare the finish to that on my 40 year old red kettle, the difference is night and day. Even though 40 years old - and with a few chips and scratches that show its age - the finish on the red kettle is THICK, shiny, and smooth as glass. In comparison, the new crimson has an almost flat appearance, and the finish has little of the feel of porcelain. More like painted metal.
I wouldn't give my new crimson much chance of being around 40 years from now, but I think my red kettle could make it to 80 if kept clean and stored properly. A sad story of how it is true that some things just aren't made the way they used to be. Whether this crimson will fade faster, I don't know. A lot of black gas grills and kettles, with nice porcelain finishes still fade. But, the finish on my crimson doesn't inspire a lot of confidence.
