All cars need to see a professional detail service at least once if not yearly depending on use and abuse from the owner making simple washing mistakes. Like Frank points out Autopia is a great reference point for how-to’s. I detailed cars back in 1985 for years for a large service in Florida that handled dealers new & used inventory and had a high end custom shop for private customers. I even watched as they backed a GNX off of the car hauler for the GM dealerships in the area and consulted with the guys at that Buick dealership on how to prep it for sale. There is no substitute for a skilled, practiced, bonded & insured, and knowledgeable Automotive Detail Professional. Try finding a service in your area that is recommended by dealers, other enthusiast, or a quality painter, you will not be disappointed. Take a moment to visit his shop, speak with him on your expectations and what he overall recommends for your specific car. It will cost upwards of $120.00 but that will include a complete detail. After the car is looking great maintaining it will be a breeze. All you will have to do is decide on what professional products you want to use. There are numerous opinions but 3M, Zymol, Zaino, & Klasse are a great start. I have recently moved to Zaino products as it did a great job on my daily driver 850 Volvo. It had years of neglect when I bought it and after buffing it with Trizac, then 3M rubbing compound, I washed it down with Dawn, and then applied two coats of Zaino Z2 Pro that I won at the Kirban Reunion. It looks really good. I will now try Zaino on my 87 Turbo T ASAP.
