Now THAT is impressive.(Turbo-Torch @ Apr. 02 2007,19) I checked out a spiral bound book from the library back in the mid 80's called "Car Beautiful". Best damn book I ever read on the subject. One thing it mentioned was to use cloth baby diapers to wash the car and put them through the wash several times before using to remove any starch. Also always go in straight lines when washing and applying wax/polish, never in a circular motion.
A lot of common sense stuff too like wash from the top down, change out the bucket of water frequently and if a if a rag touches the ground you throw it out and get a fresh one.
Here's a picture of my car that turned SEVENTEEN YEARS OLD back in November. This is the original factory paint, I challenge anyone to top that!
I like the corn starch idea. Any tips on how to work it? Mix it to a paste consistancy or thinner? Work it until it's dry, or keep it wet?(CAT3 @ Apr. 02 2007,20:11) Garage kept is much easier to maintain. I would recommend Zaino Brothers products as well. Basic technique: Wash with dish-soap and clean prep'd diaper (as mentioned above) or microfiber. rinse. claybar it until your elbows can't rub anymore. rinse with hot clean water and thoroughly dry. then start the polish process, I suggest if using Zaino to get the accelerator which greatly speeds up the drying time of the polish. Apply at least two complete coats, in the straight horizontal line technique (also mentioned above). Good luck.
I have had success on black vehicles using sifted (to break up any clumps) corn starch and polishing wheel with light pressure.
I would like to know about the 3m. I have a black truck that shows everything. Took it to be professionally detailed and the clear coat now has swirls now.(MrSlug @ Apr. 02 2007,23:49) I use a professional 3M product that many body shops use. It is available at automotive paint stores. It is mildly abrasive to clear coat and works wonders on clear coat scratches and swirls. I use a micro fiber towel to apply/remove it with elbow grease. After removing the scratch I follow it up with a good quality wax.
If you are interested, PM me and I will look out in the shed tomorrow to get the exact product number for the 3M stuff.
