Yeah,, you are right. In karachi, dust is a major concern. What if I use 3M performance finish after waxing ?? Would that seal the shine for at least 2 months ?? I mean I have no issues cleaning the car with proper car shampoo ( I use Formula 1 ) but I wont need to wax it again and again for at least a couple of month if I use a sealant like 3M Performance finish.
Generally this is what I do,
Wash with formula 1
Meguiar Show car Glaze #7
Turtle platinum liquid wax
Now planning to use 3m performance finish .
