The 3M is warranteed for 5 years. Some brands are warranteed for the car's lifetime. They used to use the film on helicopter blades in Viet Nam to protect them from flying debris and then started using it on cars and other things.
I think it lasts way beyond 5. I also get the protective vinyl applied to the headlights. It prevents breakage on those, too and as we all know headlights are expensive. The MINI has xenon lights and I know those are expensive to replace.
When I had the Porsche I found out the headlight glass replacement was $1400. The $49 it cost to get them protected was well worth it. I paid that amount for the Cube's film too.
I tried applying precut film to my MINI's lights, but they are so curved, especially the foglights, that it was an impossible task for me. I brought the film to the professional installer I use and even he had problems with the curves. One problem with the precut pieces I bought was that the film was thicker than most and it made it difficult to mold over the curves. When he had such trouble with the almost round foglights I suggested he use his materials instead of mine and that made the difference. It was still difficult, but it worked.
My installer has been doing this forever and he always has the most interesting cars in there for graphics, bras, etc. He does every police car in the tri-city area including the tribal police cars.
I'm starting to feel like a regular there as I've had all my cars done by him as I could afford it. I had the MINI bra put on at the dealership, but the price difference was $500. Dealerships give nothing away, so when I got the Cube I knew I would have my guy do it instead.
Also, useful info on this site was a link to a warranty site in Santa Rosa. My dealership charged me nearly $1700 for a 60-month 75,000 mile warranty. That same warranty through Santa Rosa is $549. I cancelled my dealer warranty and they agreed to lower the cost or I will get it from Santa Rosa.
That savings will pay for all the detailing I had done to the Cube, so I have this forum and that particular Cubee to thank.
