Ok finally I bought 3 things from Canadian Tires.
1. Meguiar's Paint Cleaner
2. Meguiar's Polish
3. Meguiar's NXT Tech Wax
Now I know how to use a wax but haven't try those two paint cleaner and polish.
1. Paint Cleaner
should I just apply those on the car and wait until it dries? Then wipe it with micro fiber tower?
2 Polish
Same direction as paint cleaner?
I was thinking should I buy a clay.. but I decided not to because I think those 3 products are enough for me..
