If one loves waxing their car and does it regularly then ceramic coating is not for them.
But if someone waxes very rarely or doesn't even bother to wax then Ceramic coatings have a lot of benefits. The weather in Pakistan is extreme. We have a lot of sun and a lot of contamination in the air which sticks to the paint during rain. The paint will get oxidized and rough quickly if not taken care of. Waxes do not last long in our conditions. Ceramic coatings are more durable and a better option in this scenario.
