Hello, I have the best solution for you. I bought a new Kona Ultimate that I have not received yet. The roof is red and I'm going to put it black. I am going to wrap the roof in black at "MG Vitres Teintées Ltée" in Laval, Quebec, Canada. They will put a permanent black vinyl over the paint. Like this, my car will not lose its guarantee, will not be derpecied because it will keep its original painting. The original painting will be protected. Plus, it does not cost too much. The good companies I know who make this product is "3M" and "Avery". Look for "Wrap 3M" in Google. The most important thing is to find a good installer. My English is not perfect because I am a French Canadian. We speak French in the province of Quebec in Canada. It remains for me to choose whether the roof will be matte, gloss or satin. I will probably choice the "3M 1080 Satin S12". This is the best solution for the top of your car !!! Have a nice day !!!
