Masking is key to a project such as this and Tamiya’s low-tack tape is ideal. It comes in 6mm, 10mm, 18mm and 40mm widths. There are three white tapes in 2mm, 3mm and 5mm form for curves too. It’s best to arm yourself with several different widths. The Tamiya masking tape can be cut easily. Make several narrow strips of tape as these can be formed around the curves easier. It is critical to have a straight edge and sharp blades, to prevent any feathering at the edge of the tape. Make several different widths and lengths, some longer than you’ll need, and some very short sections.
