Automotive water-repellent coating product recommendation

Hobby

You can't really see the windshield when it's raining, but I heard it's good to put water repellent coating on it.

I think it will cost a lot to leave it to the company, so I'd like to try it personally. What kind of product should I buy to coat the water-repellent car?

Please recommend a product.
