This stuff is the bomb it's hella hard to get off wood and metal and all things worth tagging. I have a wood board in my backyard which I do all of my graffiti practice on and I wash this thing scary now and then with a 1200 psi pressure washer. This thing gets everything off every surface except for flame off a wood board like I could not get the paint off with out cutting the board it was crazy but awesome I highly recommend this product for anyone who wants their sh*t to stay where u want it
I've only ever had the black in this model. I've had three of them. I usually ditch them after the barrel gets dented. It ships a little less than half full. The second one I got I immediately unscrewed the top and topped it off with some Garvey. Only fill about 2/3 of the way for best results. Seal with a wrap of black electrical tape after screwing the cap back on. Once the nib gets juiced this marker doesn't need a full pump, or you'll be spilling ink everywhere. I can usually do like half pump very fast, count to five and write. If you go half and half with Garvey and a nice black ink of choice you get a really nice purple fade effect toward the end of your tag. I most recently refilled with some violet ink out of a flowpen and mixed it with some eggshell es3 ink. Favorite surface is the plastic bus stop signage and white tile. I love doing tags on tile. It could be cheaper but it's not wildly overpriced like most krink stuff. I typically boycott krink products due to price, but I really like this marker.
