Fairly easy, but 2 people makes it easier.
Suss out what gap you want in between (i chose 2 inch)
Clean the area
Put 2" tape STRAIGHT down centre line of the car, spend time doing this, it WILL pay
Expose 6" of tape and line up with start position allowing for overlap of the edge of the panel, fasten the first section gently lining up with edge of masking tape (leave a small gap eg 2mm)
Pull reel tight at a 15 degree angle from the bodywork, slowly expose more tape and get 2nd person to rub stripes ACROSS at the touchline, slowly moving up the tape, rubbing side to side, firmly, with a soft cloth (lint free jobbie), keep going til you run out of panel or tape lol
Rub tape applied more firmly than you have done in previous step, until smooth
Any bubbles, pinprick an edge of the bubble, and push the bubble to the pinprick,hey presto
Repeat for next panel etc
Remove masking tape
Crack open a cold one
Stand back and admire
NB going over the edge of the tailgate will send the tape in an odd direction because of the compound curvature, do the back first and cut the tape, match the lid stripes from these and cut off excess
