Clear protective film anyone?

[spacey]

My 528 now is too old for it to notice, but the X5d I am about to order I plan to stick as much clear protective film to as possible. At least on the hood, bumpers, definitely headlamp assemblies and fogs, side mirrors and anywhere else I'll think of. The idea is sound I believe, but I have not had any actual real-life experience w/any of the countless products. IOW, are they reliable, do they stay on, do they really not discolor like they claim, are they difficult to install (does it matter? if you have someone install it), etc etc.

My question(s) is(Are) - How many of you had any experience w/the clear protective film (like Stongard, Clearshield, BMW, and there are bunch of others) and which brands/aspects of the installation would you recommend (or not), any other experiences - good and/or bad - could you share w/someone researching the products?

Thank you for any info you choose to share,
