Krylon: Krylon makes many different varieties of paint, including various fluorescents and metallics. Compatibilities mentioned here refer only to the “all-purpose interior-exterior paint,” (the ordinary kind). For the specialty kinds, you’re on your own to determine which caps do and do not work.
Krylon’s main asset is its price. Krylon spends money funding an anti-graffiti campaign, and whether you use their paint legally or not, you pay for this. Still it is cheaper than the two brands noted above. It works with every cap here (though the German Fats and German Pros can be too heavy for the paint, and drip easily–use Rusto Fats, New York Fats, and New York Thins instead). The paint is thin and drippy compared to the primo brands noted above, but thick and strong compared to those 99-cent “value” cans.
