If using electrical tape...be SURE the paint being taped if fully cured or it may peel off when tape removed.
Another great tape for using on curved surfaces like NC tips is pin stripe tape in auto department Wally world, Pepboys ,Auto zone, Amazon, etc.
Very elastic/stretchy and works as clean line maker or striping on it's own.[cheap also]

It's very thin, after laying out , you must add masking tape of your choice for full coverage. Pin stripe tape will just give you a perfect clean curved line to paint to.
It's very thin so when spraying over it....use a light mist coat to seal, let dry,then regular coat over that.
If you hit it first coat heavy, may pull paint when removed.
Few examples;
used colored elec.tape to enhance color break between orange and black to make it pop. A differentiating break always looks better. white and black 1/2 in tape.
