This cap sprays a medium line. They work well with the female Rustoleums. They will NOT work with Montana, Belton, Flame, or any European spray can. They are mostly good for bubble letters, quick fill- ins, and sometimes outlines. 5 of 5 Stars!

THIS CAP IS A MUST HAVE!!!!! I say that because you never know when you are going to have a can that a nyf will not work on. I use a lot of regular valve rustos so this cap come in handy a lot. .........Besides that new york fats ,new york thins and rusto fats are the only caps you really need........ Screw fancy paint!!!!! 5 of 5 Stars!

Awesome on hardware store paint. This is awful on actual paint meant for bombing. It gives a soft spray and locks up on the can after you press down. Only use on hardware store paint with a female valve. 3 of 5 Stars!

Question: Can u use these anymore?? Rustos are male valves now ??? Nd they dnt work on graff spray paints
Answer:(AP Reply)This will work on old school Rustos. The NYF has now become the most compatible cap with most Euro paints.
Question: When I try to use this cap on some ironlak , it just spills and makes a mess. Why does it not fit right ? Is the can messed up ? Or is the cap not suited for ironlak ?
Answer:(AP Reply)This cap is NOT compatible with Ironlak. Switch to a NYFat.
Question: Do these caps work the same on Mtn Hardcore-2 and Mtn 94, as good as they do on the original Mtn Hardcore? And what country are these caps made in?... USA? China? Germany?
Answer:(AP Reply)No not really. They work ok on HC2s but wont seat on 94s.
Question: Would these work good on quick color?
Answer:(AP Reply)Its been years since I used Quick Color, but they used to work on them. I doubt thats changed.

Question: hey i know this is kind of a toy question, but can you use 1 cap on more than 1 can? even if there different colors? thanks
Answer:(AP Reply)sure
(smoke-n-paint Says:) yeah i do that alllll the time just be sure you clear out that cap first by spraying upside downyeah i do that alllll the time just be sure you clear out that cap first by spraying upside down
Question: Can I cut and drill this like an ny fat in the video because the stem on one is the exact same size as the valve piece on the new rusto can.
Answer:(AP Reply)no they are from completley different molds
(Anonymous Says:) yeah, sadly i guess ill just have to use hardcore or drill ny fats or buy ap female fats (you should call em bill clintons) goodby stops rust 33% more cans.yeah, sadly i guess ill just have to use hardcore or drill ny fats or buy ap female fats (you should call em bill clintons) goodby stops rust 33% more cans.
(Anonymous Says:) so basicly... rusto has made there cans not compatable with the caps named after it... i guess its time to stock up on the old cans while there around!(aprepyl) Well rusto has nothing to do with these caps. Its an old slang term. They work great with Valspars new cans, OSH and MTN Hardcore. so basicly... rusto has made there cans not compatable with the caps named after it... i guess its time to stock up on the old cans while there around!(aprepyl) Well rusto has nothing to do with these caps.

Question: i hate that these r the onnly fat caps that work on rusto's. Can AP make a fatter cap for rustos. THatt ll be SICK!!!!!!!!
Answer:(AP Reply)fatter isnt better if it doesn't cover well. Rusto fats fill clean and are fat enough. Belive that
(Ma.destruction Says:) I can probably assume none you guys have ever been to Ma. or New England, or you would know about the BOSTON FAT...try them out,they're made for female Rusto cans and they def flare a little better.(apreply) we are aware of them.

Question: are these really good for flares or are there better ones
Answer:(AP Reply)no. not a flare cap. Its a high volume filling cap. If your using Rusto then this is what you get. if you want flares then try some Old School Krylons or the Montana cans with a NYF
(Ma.destruction Says:) Some people aren't aware of this, but Krylon still makes female cans.The Metallic colors (chrome,copper,gold and stainless),and all the"specialty cans"are still female valve,you just gotta look for 'em.Some people aren't aware of this, but Krylon still makes female cans.The Metallic colors (chrome,copper,gold and stainless),and all the"specialty cans"are still female valve,you just gotta look for 'em.
