What should I do about this situation?

One of my guy friends keeps hitting on me. I’m not interested. My feelings forbid it in every way possible. He’s morbidly obese, physically repulsive, completely bald and middle aged. He’s also not very intelligent and gets angry easily. He seems to take any kindness a woman does him as potential interest. I like him very much as a friend and I don’t want to hurt his feelings, but I feel like I should have as much right as anyone else to reject someone because I feel no attraction, physically or mentally and have it respected. How do I deal with this kindly? Just see him less often and keep brushing it off? Or have a real word to him?
