Winter is the harshest time of year for your car.
Corrosive road salt, stones and repeat freezing and thawing can wreak havoc on your painted sheet metal surfaces and your under car floor pan, critical brake, fuel, exhaust, unibody and subframe components. To compound the matter the cold winter probably kept you from washing your car as often as you should have.
April is a good time of year to bring your car in and have the underside thoroughly flushed to remove built up salt from nooks and crannies.
This alone will add 5-10 years to your vehicle’s life and increase it’s resale value. At the same time, the underside can be checked for rusted components and adequate rustproofing protection. Remember most factory non oil based rustproofing starts separating from the underlying metal sometime between year 6 and 10 necessitating blowing or scraping off the product and recoating with an oil base one. Contrary to popular belief it is not necessary to rustproof the entire vehicle underside annually. Only the dry or rusty areas on the vehicle should be rustproofed or you will end up with a build up of dirt that absorbs the oil and the underlying metal will rust. Remember once a film of oil is applied to any metal surface, oxidization is interrupted and further rusting cannot occur. We use Krown T40 industrial formula and Rustblock when rustproofing your vehicle.
