Armor all Ultra shine wax and wash detailer. bought for around PKR 520 from hyper. recommended by @Accord and rightly so as I am pretty happy with it.
Sorry I am answering this for V1...
Broad is actually right and it cannot be narrowed further (IMHO) because the post was on general terms.
Quality is different for different people but safely you can say 'stick' to ones which are 'original' and of reputable brands which are built for performance and detailing connoisseurs rather than price and budget conscious users.
What is the right one? Well...to each his own...what might suit your ride (color, condition, number and type of paint coatings and WORTH OF RIDE plus the result required) and application style might not suit me...one man's all natural carnauba dream can be another man's nightmare. Me for one knows that I will not like handling hard wax...so whatever the quality I'll never go for it.
But anyways a small category level to help you narrow it down
The Snob class (I won't name the brands here...irrelevant for us)
The Elite specialist class (mostly imports) Dodo, Megs, Wolfgang, Pinnacle, to name a few
The generalist performance class Turtle, Mothers, 3M
The detailing Entry level class Speed, Sonax, Armor all,
The budget class - the Kazmics, formulas and yes even my soft 99...
V1's comment on quality product was pointed towards me as he knows I am using a not so cheap but still chinese type product but then he knows about the range which is coming my way.
So bro, logic says that the higher class you'll go for, the better the results...but product plays a key role but so does the applicator and the car it is being applied on. The top four categories (quality categories) will not leave you with any handicap and drawbacks of the product itself if you know what I mean where as the cheap ones in the budget class will....and that is what V1 meant with his statement.
