Best place to buy vinyl wrap

Going to try to wrap (the back half) of my roof gloss black

My GTI is white with pano roof and I don't like the half black/half white roof

Looking to buy 3M (or anything else that someone might recommend....vvivid/Avery/ etc)

I am going to do this myself. I am pretty handy and from watching 1,000 YouTube vids I am confident I can do this. I am, however, ordering TWICE as much vinyl than I need. That way...if I fail at my first attempt...I should be able to get it on the second try (or have enough to let someone else do it). And if I'm successful on my first attempt....I will have some left over to possibly wrap other stuff (mirror caps, etc)

My main concern is getting a good product

Looking on eBay and Amazon.....I see lots of good prices/deals.

But when I read reviews, I see a lot of people complaining about

*Fake/Misbranded material
*Damaged material (dirty/scratched/creased,etc)
*Poor customer service
*Etc


Where can I get "genuine" stuff at a good price?

Where do you get your vinyl from

Thanks

If you buy from Amazon it's pretty hassle free to return it if it's not what you were expecting.

I bought some 3M carbon wrap from Amazon. It was fine.

www.fellers.com is also excellent. Quick shipping, great service, good prices. Ive been dealing with them the entire time Ive been vinyl wrapping my GTI

And if you haven't placed an order yet, i also like vvivid. Found them originally through amazon, but i've since placed orders through their webshop. Seems nice enough with a good variety of material.
