I own a few vintage cars, each of which i drive regularly. Blue 1975 Fixed Head Rolls Royce Corniche, White 1970 Series 1 Lamborghini Espada, Orange 1973 Series 3 Lamborghini Espada.
The cars are washed with the recommended swirl-free foam sponge and Tech Shine is applied. Takes a mere 5 extra minutes and applied while the cars are still wet.
The Tech Shine result is like a mirror. Super easy and provides a truly amazing finish. Nothing compares to Tech Shine.
I searched and searched to find ANY review of your Tech Shine on older cars/trucks with not-so-great paint. I found none.
Wanted to follow up with my application of Tech Shine to my new 2018 KIA Stinger that I purchased last week.
