How about this 3 year old work horse.
Now wearing Angelwax Limited Nebula Graphene accredited installer coating.
Advantages of graphene over SiO2 ( Ceramic coatings ). Is water behaviour and gloss levels . Sadly this a premium product due the difficulty in producing Graphene so it will be more expensive to buy in & install 👍
Otherwise has the same advantages as Good Ceramic Coatings that we are now using from System X USA.
