Find a good quality detailer to remove the swirls.($150-$300 depending on location and severity of swirls) Request a sealant application(Should last for 4-6 months). Read the how to in washing your car weekly/biweekly with a two bucket approach and sheepskin washmitt(my choice. Many other wash tools, but just easiest for me). Apply no pressure with a good shampoo(I love the
Meguiar's Gold-Cheap and suddsy). Just let the weight of your hand glide over the car(not in circular motions). Rinse well and dry with waffle weave towel.
With the proper technique, your washes won't create new swirls. Sheepskin mitts are $5-$10 and should last you 4-6 months as well. Same with wash. $10 for a gallon(or half gallon, I forget) Waffle Weaves were I think $22 for the biggies(I use two to dry. One for most and 2nd for the 2nd sweep) Upkeep is cheap. Getting to a good clean and clear surface is the key.
I've gotten washes and dries down to 45 minutes. I'm a little stupid cause I like to clean the entire inside of the rim(still have new car syndrome) so without this part probably 30 mins. When I'm done, people ask what kind of wax I use. I applied 3 coats of
Klasse SG almost 2 months ago and it still looks like I just applied it after each wash and dry.
