I turn the thing i powderd upside down and rub the powder off of the tape with my hand as much as i can then take the tape off while it's still upside down so no powder goes anywere but down on the floor. and everything i have done like this looks good. and i clear coat it all when done like that. and the lines are not bad at all. people pay me good money to powder coat designs on things. i will take a pic of the next thing i do if you still want to see how it looks. but by then you may have powder something like that your self. no one has came to me with anything to powder in over week. im getting board here.
