So, I've installed clear bra solutions on 4 of my previous vehicles. The only template I gave up on was the lower bumper on my 2012 Msport X3 35i - what a nightmare. I've done it on 330i, Kia Sorento, Mazda, etc. (I have a 2012 Golf TDI - tech package)
Anyway, I've never really found a product I liked until I started using the Venture Shield product provided by invisible mask . com . There are a ton of companies and bunch of films out there for sure it's difficult sorting through them all and trying to compare.
Currently their site has two template/kit Catalogs (#1, #2). When taking a really hard look at Cat #1 2011 Golf templates vs the Cat #2 2011 Golf templates (because they don't list anything for the 2012's yet) I liked the price and look of the Cat #1 2011 Golf 2.0L 4Dr template.
I just finished installing it and wanted to put some comments and thoughts out there for others who have been brave enough to tackle installing clear bra solutions themselves.
The install went great. I installed on mirrors, headlights, side fenders, lower bumper, hood and yes, REAR upper bumper guard. As always the lower front bumper was the most difficult but with my past experience of about 3-4 other installs I was able to nail it perfectly, even without a second set of hands (which I don't recommend- always have a helper if possible).
If anyone has any questions or thoughts on this let me know. My local tint shop wanted over $550 to install the 3M product they had, I got all of the above plus rear bumper for around $350.
Anyway, went on really nicely, the film is EXTREMELY forgiving, pliable, strong and looks fantastic. Photos where my mouth is:
