This is definitely one of the best brands of permanent vinyl that can be used for car windows (or anywhere else on the car body). It is a premium vinyl that can be used whether your car is kept outside or in a garage.
Oracal 651 can be purchased in a wide range of colors – black and white vinyl being the most popular for vehicle decals. It is also for sale in sheets or rolls of varying sizes.
Cricut vinyl is another strong vinyl that can be used outside and on cars.
While this is a craft vinyl, it’s still very hard wearing. We have used Cricut permanent vinyl on many, many mugs and cups. These cups have been through the dishwasher (without being sealed) a hundred times and still look perfect.
The downside to Cricut Vinyl is that it only comes with a maximum width of 12 inches. If you want a decal wider than that we recommend you go with the Oracal or Siser vinyl.
