Hi guys, normally when you machine polishing the paint, polish/compound dust tend to be all over the paint. How do you tackle this problem especially on panel that haven't been worked on but were full of polishing dust?
Wipe them away with microfiber + QD first? Kinda time consuming ler

If they're 'loose' and you plan to polish the panel, just a gentle swipe (not wipe) on those parts with a plush microfiber cloth before polishing is fine. No need for QD or anything.

What is the best coating available? How come some as cheap as rm 300 and others like 2k++?
What should I get for a new white car?
Not many coatings are available to purchase for DIY. Those that are ranges from around RM200 ~ RM400. For these you can find plenty of reviews online. But many shop nowadays are using those that cannot be purchased and, for these coatings, curiously, not many reviews/feedback from users. Another thing to note is some shops that uses normal wax/sealant also boast the word 'coating'. The reason being, they're using products from Taiwan, Korea, Japan, etc. which, on the label and by direct translation, would means 'coating' but in actual fact they are waxes/sealant. I'm guessing the cheaper 'coating' jobs are using these instead of the 'true' coating.
Again, for a new car and if you're just starting to get into taking care of the car yourself, concentrate first on washing and maintenance - shampoo, wash mitt, all purpose cleaner, drying cloth, etc. including the proper techniques and methods.
