So....how easy was the application?
Over here, it's NOT OK if you DON'T wash your car once a week....

Joking aside...yeah...you're fine washing once a week, provided that you do it properly. Did somebody tell you there's side effect of doing this?

Wash every week should be fine. Not sure about waxing every week. Recommend to wax only when water doesn't bead anymore. (Afraid that wax without claying first might cause some swirl marks).

I am new on polishing too  You can either start doing it by hand or by machine (recommend using DA polishing tool instead of rotary polisher first). Ultimate Compound and Ultimate Polish are good products to work with, IMO.

Common procedure: wash->clay->compound->polish->wax/sealant

You may skip compound step if there are no severe scratches/swirl marks on the car paint.

Hi, new car? No problem to wash and wax once a week, but possible try to wash twice a week And wax monthly, i found if u wait a week to wash, the acid rain already build water mark at clear coat even with a wax, and maintain a surface with quick wax water base if possible and do paste or liquid wax once a month,

Example of good quick wax is, turtle wax it wet, and meguairs ultimate quick wax.

Your damage has already gone until the primer.
You'll need to paint touch up first.

Dun think its possible...as paint has gone

Plenty of them are using Karcher.
