Im after wrapping the grill on my octy mk1 vrs along with some interior bits. What wrap is best to use?

I would use 3M di-noc- It's a bit more expensive but really nice to work with under heat.

I used white 3M, 3D, bubble free, plenty of choice in sizes on ebay.

Don't use di-noc, it's not the right stuff, if going for 3m, use 3m 1080 wrap film.
