I'll comment on good places to buy vinyl in about one week.. I just need to see howe my "stiped" vinyl situation plays out..haha
It cleans really well, I parked under a tree the other day and sap came off easily. It does scratch easily, moreso than paint, and because its matte its more visible.
While applying it, its very important to "stretch" (you don't really want to stretch it much at all though) evenly, or the differences in the sections will be obvious (normal matte->getting glossier).
I've used diNoc vinyl..its a lot different to work with and a lot thicker..makes it better and worse. The thing to watch out with that though is over large surfaces, if it isn't uniformly stretched, it will be really obvious in the "CF" lines..they won't be straight
