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
this things a f*ckin boss its super wide and is great for huge tags and f*cking sh*t up. the only problem that i have had was the nib fell off a few times but that was because i make my own ink and its a little harsh so it caused the nib to fall off but besides that this thing is dope.
