Ceramic coating is honestly the answer. It will lock that colour in and it will look like the paint is wet and glossy for 5-7 years. Won’t scratch and your cleaning process will be done in twenty mins. No need to polish the car. No brainier..Here’s mine. Original 1989 paint ceramic coated. Stays like this. Wash, beads like hell and dries off in a few mins to look like this from dirty . All I’ve done is wash it. No polishing . Think what your stunning car will look like it . Standard photo , no photoshopping or clever stuff.
