My new red 2018 goes in for 3M clear tomorrow.Only 18 " up on the hood ,fenders & "A" pillars.Also putting a piece on the hatchback so the finger prints don't make a mess every time I close it .I've had several different light & dark colour cars with the 3M clear & never had a problem "seeing the line".When I wax/polish the car I have to catch it with my finger nail to find it, then I use painters masking tape on the edge of the 3M tape so the polish doesn't build up at the tape edge.Even if it does, a tooth pick of soft toothbrush will clean it out.
