Saw this decent deal in the coles catalog.
Think it's usually from Wednesday to Tuesday so may be expiring Tuesday
But it's decent deal.
Use this to take advantage of SCA/reject shop price beat if you want even cheaper
Straight wash is best
In what way?
Can't say a wash and wax has ever made my car look dirty if dried properly as per the instructions.
Wax on wax off
Maguire soft wash gel is good
