Well Ken
This is the big problem for so many of us with red heads. I have the same issue right now with my 26". The problem is that there are so many shades of different red with these grills throughout the years, that you may have to buy different cans from different manufactures just to get it close enough that you are happy with it. You are also limited on the high temp variations of reds out there. One thing that is important though...when you are testing different shades of red....make sure you test them in a well lit area...preferably in the sun. Ive made the mistake of working on one in my garage, then when I brought it outiside in the sun, the touch up color looked TOTALLY different. Good luck
