I can't believe no one here has ever used a product called "REJEX". It is the greatest for wheels and getting bugs not to stick so bad and is just great for the entire car.
A bottle goes a long way. I have it on both of my vehicles and will be using it on my new H3 as soon as I get one. It lasts on my vehicles for about 4 months.It is so easy to apply. It can be found at
