||this sh*t is great for piecing. it gives you great control with rusto or x2 cans.
like the regular female fat, if you want to use this on rusto or x2, pop the blue collar off and push the cap on the valve until it snaps. the paint will come out a bit while doin this, but dont worry you wont use up that much.
i love using these guys for outlines of my pieces and for all around borders. its also good for fills.
i have found that these dont clog quite as easy as the v1 female donut fats, so in the future, i think i will be using these more often than those for the the fills too.
although i havent used them a whole lot, i have done 3 pieces with these ez riders. the second two times i used it, i re-used the cap for both outlines. if i did this on the v1 donut cap, it probably would have clogged. thats why i like these.
on the first piece i did with it, i used this for the outline, and i started to do the fill with this, but i switched to the v1 female donut fat instead, which i seemed to like better for that piece, although it was the first time using this cap... now these are great for the fills imo, so take that with a grain of salt.
on the second piece, i used this for the fill and the outline and it was fat enough and turned out great.
my recommendation would be to get these and the v1 female fat cap, and also the softie white/black fat cap and try em all out to see which you like best.
im going to take 1 star off the review because its a bit harder to take these out of the housing without fear of warping or breaking the cap while twisting/removing the housing ring. i've remedied this by using a knife or a leatherman to cut the bend that connects the cap to the housing. the donut fats just snap out easy compared to these;but that is my only real gripe with these caps.
all in all these are an awesome cap. get them if you want to turn your x2 or rusto into butter machines; everyone loves butter.
