The AP Precise Cap offers the thinnest line available with a female cap and it is amazing for detail cap. Please note: although it appears similar to the stock cap on Rustoleum Painter's Touch, the effect is entirely different- don't be fooled! This cap performs on many spray paint cans with MALE valves and we have personally tested it with Painter's Touch, but cannot guarantee it will work with all cans as Rusto valves may vary. A must try!
Here/s what the GR has to say about these caps;
"Imho that cap is better than ANY adapted thin tip. Fits directly, more control, less overspray and no wonky finger position. "- on Rusto
