My go to cap for everything! I order these by the 100. These are for rusto heads and don’t work on fancy paint. These stretch a can, get tight lines and flare great. I’ve had homies that say they aren’t a fan of the delay on these but I’ve never had an issue. Bonus point is also you can get insanely thin lines once they start to clog. 10/10  5 of 5 Stars!

These and Boston fats is all you really need if you're using Rusto. Solid lines for outlining. If you know can control then you'll love these. And they don't clog as easy as other caps.  5 of 5 Stars!

Years ago I used to find these on glue spray cans in Menards, then they started floating around the internet as "Boston Thins." Really the best thin cap for rustos with the old valve system. A black rusto with one of these feels better than any fancy euro paint for thin clean outlines.  5 of 5 Stars!

This cap did not work well with the Montanas. It gets stuck. With the Rustoluem I tried it, and the spray was very thin. I sprayed it from six inches away and it gave me a dot the size of a normal eight ounce cup. The line had been very thin when sprayed from the Rustoleum. The out-put had been less than one inch thick. The are good on Rustoleum, only. Thesse caps are good for outlining, fading, and shading.  5 of 5 Stars!
