I've been applying protective films to cars for over five years-- while the 3M spray film does not protect as well against large rocks and objects that would generally be stopped by thicker film, it does work exceptionally well and is much faster and easier to apply. When applied properly, it is completely clear and invisible even on dark paint. It is also very easy to remove and leaves no residue or paint damage when removed-- unlike cut film which will often lift paint repairs.
For best results, you should familiarize yourself with how these viscous films spray-- they are nothing like spray paint and must be applied differently. You don't really need the spray handle, in fact I prefer to apply it without one, but you must move with a considerably slower travel speed than with spray paint, and you should leave the nozzle depressed when spraying whenever possible, unlike the short start/stop passes used with spray paint. This prevents most blobbing and nozzle foam and leaves a very good application layer.
Temperature also plays a huge role in cure time and finish. I prefer to apply it "cool" at around 60-65 degrees, then once applied crank the heaters up to 85-90 degrees to aid curing. If applied thick it needs at least 4-6 hours at high temperature to cure to the touch.
While 3M recommends a certain amount of film for various areas, e.g. one can for the front nose of a car, I find that using twice that amount in two heavy coats leaves a much better looking and durable finish. This stuff looks horrible if you put it on thin, so I recommend purchasing one can more than you think you'll need and go over everything with a second coat once the first coat is shot.
Note that proper masking is key, as is waxing. It is a good idea to get two different colors of low residue masking tape when using this product so you can use a different color for pulling the cut lines. That way it is easy to make certain you have pulled all the needed cut lines while the film is still wet. If you let some try to tape with no gap between panels, you'll need to lightly score the film with a razor blade prior to pulling the tape. Given the risk of cutting plastics and paint doing so, it is much better to use a different tape color and ensure you pull everything before it dries.
I'll definitely be using a lot more of this film. Even if you replace it every few months, it still offers the majority of the protection of a cut film at a tiny fraction of the cost, with a much nicer finish and easy application.
