A magnetic car door guard should be used if you want a temporary product that will not change your vehicles appearance. In comparison, stick-on car door protectors are permanent, so you cannot remove them easily once installed. One of the biggest advantages of magnetic car door guards is that they offer superior protection and are thicker than any stick-on car door guard you will find. Use a magnetic car door guard when you need it (i.e. after you park) and remove it before driving. Door Shox magnetic car door guards are the best car door protector out there. Not only is the product flexible to absorb impacts, its magnet feet have a ribbed rubber coating that’s super easy to wipe clean.
