Our HoA community parking lot lines are wearing off, about 5 lines, and I'm interested in respraying it instead of calling a professional.
I bought a Rust-Oleum Professional White Paint Spray, and I'm not sure how to avoid over spraying, all I can think of to get the job done is to use General Purpose Masking Tape (ones they use for painting) but that'd likely require at least 3 lines of tapes for each side of the parking line.
Make a stencil. That what road markers typically use for arrows, symbols, letters and numbers .
Easiest would be out of some cardboard boxes. Flatten the boxes, cut them and create a stencil with a gap shaped like the stripe. Place on the road, spray paint, then re-position for the next stripe.
