if you get the tape, an you stick it to a clean surface a few times it will loose its tack, altenatively you could buy yourself some low tack lining tape from your local bodyshop stores likes of southern paint supplies or leonard brookes paints
that will not bleed like normal household masking tape and is designed for lining onto hardening fresh paint in the paint booth.
Im personally yet to see a set of joey'd lights brush painted that dont look gash close up no matter how many coats you put on, willing to be proven wrong tho guys please do tho maybe your craftmanship is better than the ones i have seen so far, however you can reduce the brush strokes in the paint a great deal by putting the can of paint in a pot of very hot water, this aids a smooth brush stroke, but for something like this you will need a longer brush hair & a good quality brush, its kinda like coach painting technique.
the choice is yours tho!!
