I think I got OCD judging by the no. of dirty Porsches I see everyday!! It might be inherited??? My dad is just as bad!!
Your car is black----you have to make sure if u want someone to do it for you, make sure they are professional! Otherwise you will end up with loads of swirl marks or 'spiderweb' esp on your bonnet!
Preparation
1. Hose pipe only-Jet wash+loose sand can abrase the top lacquer!!!!
2. Clean bucket and sponge. USE WARM FILTERED water not HOT!
3. Avoid direct sunlight-A perfect day will be a cloudy day (Not raining

)
with no wind.
4. Loads of wax applicator and microfibre cloth
5. Ideally someone to help you---Your other half?
6. Some good music and someone to make you a good cup of tea!
Lazy method(3 hours)
1. Rinse car with hosepipe to wash off loose dirt before applying Zymol
Autowash->One sponge for bonnet roof etc.. and one sponge for bumpers
and skirt. Another sponge for the wheels and exhaust trim.
2. Dried with chamois--->Vertical motion
3. As you never wash your car properly-->the car wash can only manage to
wash out the superficial grit, you will need something like Zymol Lehm
-tube 2+ Lehm Klay to pick up embedded contamination on your paintwork.
4. Apply Zymol cleaner wax (12% yellow carnauba)with a wax applicator
--->vertical motion
5. Buffet each panel with soaked microfibre cloth first then a dried one to
minimise the formation of 'spiderweb'-->Karate kid motion
6. Stand back and admire the shine or apply another layer.
For those with OCD(5 hours)
1. Same
2. Same
3. Same
4. Apply HD-cleanse with a wax applicator one panel at a time and buffet
with wet cloth first then a dry one. THIS IS HARD WORK!!
5. Apply Glasur Glaze 56% yellow carnauba with your bare hands. Buffet each panel with wet
cloth then dry cloth
6. Apply 2nd or 3rd layer
Hope this helps!!
