The Boston Fat Cap was modeled after the New York Fat Caps, but it also eliminates the pesky paint leakage so you can keep your hands clean. . These caps are magical, virtually eliminating the classic Rusto valve stutter problem and also have a nice low pressure feel.
These are Fat Caps for female valves, perfect for original Rustoleum or old stock American Accents and Painter's Touch cansCompatible with old valve Krylon, Spanish Montana/MTN, and most off label American brands. Great for filling in large work areas and for flaring effects.
