Yes, heat gun is essential for getting it to sit nice along the edges. It is really not that hard to apply once you have done it a few times. patience is the key, and cleanliness, don't try and rush it, it will not work if you do.
I thought about the brushed aluminium wrap, I reckon it would look great, just wanted something a little more distinguishable from standard without looking stupid.
Tried this one today and I think I like it. I think I will do the centre piece next and see how it looks, the silver one i did without removing it from the car and it looked bad, I will rip it out to do the black. If I can work out how.
