take the cap from the 360 and tear out the metal pin and slice off the little extra plastic nub/finger/grip flap thing that pushes the metal pin down,you will now have a 360 cap wit nothing to push down on just a flat round surface with a tiny hole that the metal pin once slid thru... take your gel ink cartridge and cut it a little shorter then an inch then cut it in half so now you have two half inch pieces of gel ink cartridge, now take your razor or scissors and that little tiny hole on the 360 cap from the metal pin you want to carve it in a circle to make that hole a little bigger enough so one of the half inch gel tube pieces slides in now glue to seal it tight, slide the other half inch piece of gel ink tube and slide it on the male part of your favorite cap it should fit tight and snug it did for me on most it was a little loose on the universal outlines, now cut a piece of your bic ink tube about less than an inch and slide it in your gel ink tube thats on your cap then slide that into the gel ink tube piece thats glued to the 360 cap, now your cap should be able to slide up and down, cut about an inch long piece of paper clip with your pliers and you can slide it into the bic ink tube then click the bottom half (the part with the 360 cap onto the 360 can) now your cap slides up and down and in turn pushes the paperclip piece down making the paint spray through the ghetto adapter out your favorite cap i just let the paperclip piece sit freely in my tubes between my can and my cap another option if you want it attached to your cap you can heat the paperclip tip lightly and push it gently to the inside of your cap but not too much or it pokes a hole all the way through... did that once and fucked around and threw that cap back in with the new ones by accident and trust me its no fun when you go to do a throwy and end up with blue rusto in your fuckin eye hahahahaha i was like whaaaat theeeeeeee fuckkkkkkkkkkk then i realized there was a hole in the finger part of my fatcap lol anyways ill post flicks later of the process sounds long, hard and complicated and half you stoned fuckers are probably lost back at step one with out picture refrence but it is simpler than droppin a deuce like i said i came up with the idea within the time it took to choke down a cigarette i tested it and it works with little leaks but then again i dont have any super glue on hand or it would be air tight but i was impressed compared to the fan tip 360 bullshit stock tip i just rigged a ny thin and it fit snug so i didnt have to glue which also made it possible to slip other caps of choice on...
