I replaced mine on my 300e ( will get a 129 eventually)

1. Do a dry fit first to get comfortable where the edges should go.

2. These look like they have big hoods so get an extra set of hands because once you set a part of it against the adhesive - it is there. Use 3m Super adhesive.

3. Cover everything you don't want over spray of the adhesive on - OVER PROTECT YOUR BABY WITH MANY SHEETS. This stuff is hard to get off of fenders , and engine compatment - I know.

Good luck.
