twentyfour:
Welcome to Autopia and congrats on the 2005 911 Porsche purchase. I say that as a Porsche-o-phile, but I am an admirer and dreamer (the one iconic car many WISH the could own and drive), not a real owner like you.
Here`s what I wrote in another thread about what you need to get started in detailing:
One aspect the beginning hobbyist detailers overlook is car washing and the products and equipment needed to "properly" do this detailing task.
If I was starting out taking care of a new (or slightly pre-owned, new-to-me) vehicle is to invest in vehicle washing products and equipment.
5 (or 3)-gallon Buckets, Grit Guards, microfiber noodle wash mitts,bug pads, wheel-cleaning pads, brushes of various types (one for the rim brake dust, one for the egg-crate-patterned grill, one for the tires, one for the vinyl trim or door/trunk/rear hatch jams and hinges), microfiber drying towels, microfibers for use with the various exterior cleaning products listed below, a 50-foot (or 75 foot) 3/4-inch diameter industrial/contractor-grade garden hose and spray nozzle are things to consider.
Then there are products of vehicle wash soaps, tire (or wheel) cleaning, brake dust (rim) removers, bug cleaners, All-Purpose Cleaners or De-Greasers (for door jams and wheel wells), iron decontamination cleaners, tar removers, and window cleaners to consider. That is just "the basics" in my mind. As you can see and guess, you`ll have quite an investment in these products and equipment alone. BUT, vehicle washing is the one detailing task you will do the most of, so why not start there.
Most vehicle exterior "problems" are the result of improper washing techniques or poor or neglected cleaning. How many newer vehicles do you see whose rims look black from brake dust? A LOT! Or even dirty wheel wells because tunnel car washes do not clean effectively in those areas. Or bugs on the front grill or bumpers because automated car washes do not remove them? Or even bird droppings that sit on panels or hoods and etch the paint because the vehicle owner/leasee does not care (or know) enough to use a rinse-less wash and spot clean these problems when they occur?
You can add a drying blower and power washer and foam lance as nice-to-have tools for vehicle washing later on.
(My "redneck" drying blower is a Toro Variable-Speed leaf blower, Model No. 51619. Works for "cheapskate" me. Just NEVER use it as a vacuum to pick up and shred leaves or lawn debris. It`s a mess the next time you try to dry a vehicle.
Live and learn...Or as 1920`s humorist and writer Will Rodger`s said, "I guess common sense ain`t so common!")
By the way, another Porsche 911 owner within this forum is Sizzle Chest. He is a world-class (and I do mean "world-class") detailer extraordinaire and has detailed more high-end 911`s than most people see in a life time. If you want, use the search engine within this forum, Key in "Porsche" for the keyword, and "Sizzle Chest" for the user name, and look at the posts started by him. He lists the detailing products he uses, mostly McKee`s 37, Adams, and 22ple coating, so this might give you an idea of which products to buy and use.
