Very durable. I have been doing this for years on my Chevy bowties and lettering. I have had the lettering on my Camaro for almost a decade. As for the bowties, very robust. hold up to washes and even hitting it with a power washer from afar.
@@TheDaman1111 Lucky for me I lease my vehicles. I guess that's on the next person. I have tried to remove it on other items and you are correct, it's not as easy as people think to get off.
