I think that looks awesome - and the fact that it fits over the stock one is a great idea!
What did you use to stick it on??
Also, slightly off topic, but whats the width of your garage??
My garage looks around the same size I think, and I want to make sure I can get the GTI in/out easily, and be able to open the car door enough to get in/out!!
Just had my electric sectional garage door fit as well
