I use Revive every day when valeting cars and it never fails to please my customers. Great for brand new or 10 yr old cars. excellent for oxidised paintwork as it cuts into the oxidisation and also polishes and protects the paintwork leaving a mirror finish without the need for any hard scrubbing or buffing. Revive also removes small scratches and swirl marks in paintwork. No white residue is left on paint or plastics. Excellent Gloss finish. I would say durability wise it lasts 8-10 weeks.
