You can pick up some Glidecoat Ceramic Coating here: https://www.normalguysupercar.com/product-category/garage/car-care/
I’ve been on the hunt to find a better DIY Ceramic coating. I like the previous brand I was using, but I wanted better and longer lasting. So I stumbled upon Glidecoat while looking for some products for my boat, and noticed they have lots of great automotive products as well. I decided to give their Automotive Ceramic coating a try and I’m a big fan! 2-3 years of protection for UNDER $100!
