Not sure if you would call my mop paint GK cos all it is is black gloss enamel oil based paint.
I found a little tub in my dads paint, thinned it down a bit, got my bingo marker emptyed it out, cleaned it with water, pulled out the regulator and put the paint in. Only did a quick line with it but the bit where it 1st touched the plastic dripped nicely, i went too fast for the rest of the line to drip. Gonna have a bomb with it maybe 2moro see how it goes.
I used some Dulux Black Gloss Enamel (oil based), didnt add anything fancy or nothing, no dot 3.
Also any Aussie writers, if you want bingo markers, goto the $2 Shop, they have 2 packs there for like $2.50 if you dont wanna rack em, plus ive seen em in Reject Shop aswell, only thing is, the body is hard plastic, but it should still flow/drip nicely. (Dono if anyone knows bout it)
