Great on XL krylon and valspar. Some caps dont work but i mainly use yellow thins and ny fats and they work great with both. Like the description says these can be finicky on some valves, i had trouble with the target valspar, it fit but would pop off due to pressure and had some leakage. Worth every penny and i use it all the time.
Great on plastics, metals and other items, Good coverage (though if you over cover and it gets a lil thick and can take a while to dry, even after drying if you're going over with a fiberglass tip it tends to drag the paint). I also wouldn't suggest using this for tagging if you don't want it buffed (also doesn't seem weather resistant. Still a fun marker and great quality, just have to get used to it like all mediums. f*cking lit for model trains less lit for vandalism.
Ayee this boy ain't bad, writes wet and fun as hell. The only trouble Ihad is when I started splitting em- some colors have a harder time sticking back together- it helped when I scored (cut small lines into the portion of the split that would stick back together) but some colors, specifically the neon green, still gave issues. Still a fine marker for your regimen.
