At the time of writing this, it has been on my car for a little over a week, driving thruway to and from work every day. Its held up well so far, and I have gotten quite a few looks from other drivers, and people on the streets.
I imagine that I wont want to leave it on too long to avoid excessive goo removal when i finally take it off.
Although I think that the effect works better on Orange and Black vehicles, I think that it has the potential to work well on most any vehicle with a bit of creativity.
Step 1: Materials
Duct Tape - I used Orange and Black - the orange is Duck brand and the Black is Scotch Brand. This particular Duck brand seemed stickier than the Scotch. The Duck might stay put longer, The Scotch may come off cleaner / easier
Scissors - to cut the duct tape (exacto knife and a cutting matt may be required for more complex designs)
I purchased two rolls of the Orange Duck brand tape from a local hardware store for $5 / roll, and only used about half of one roll.
The black tape I already had.
I later saw the same tape at Walmart for $3.50 / roll.
Realistically, you should be able to do something similar for well under $10
