Trakk tape :
Goes on easy enough and once i settled on a good technique which was leave tape over hanging the panel your doing and then trim back to the size you want. So for example when doing the wings i attached the first inch to the doors and then cut along the panel gap and folded in behind the wing. I found going from screen to bonnet tip was the best way and minimised the bubbles. Pop the bonnet and fold under the edges and trim as required.
No damage to report on mine at all and some evidence on the tape that it had done its job.
The only down side is if its spitting with rain when your trying to put it on then you get milky white bubbles under the tape. So if you are doing a track day and have nowhere dry to apply then it could be a problem.
Water marks on wing
Its stays on very well and is easy enough to take off.
End of day and its still all in place
