For anyone wanting a simple route to a clean beautiful car with products that can be purchased locally I would suggest the following:
Wash - Meguiars NXT or Gold Class shampoo
Prepare (once every 6-12 months) - Meguiars Clay bar (use with Quick detailer)
Wax - Meguiars NXT liquid wax
Wheels - for stubborn brake dust Meguiars Hot Wheels (non-corrosive wheel cleaner
Interior - As per my previous posts, but just buy something that doesn't make the dash shine! 99% of the time, I just use a damp chammy
Einszett Cockpit Premium
Leather - Gliptone Liquid Leather Conditioner
In between cleans if your car has a nice layer of wax you can use Meguiars Quick Detailer and simply spray on and wipe off any dust. I only do this if it hasn't rained in between, if it has I just wash the car as per normal.
