good day to all sifu here, just did my first full DIY car detailing - car wash, clay, polish and wax on one of my car.......with satisfying feeling but not really wet shinny look result, what did i do wrong or didn't do right.

i did this on my proton iriz (metallic silver car) after-work and dinner, for 4 days start at 7.30pm till 11.00pm (or until too tired to continue) and before continuing the next day i will just rinse the car first.

method :

1 - full car wash with normal car shampoo (bought from jusco) on first day only (using micro fiber cloth and 2 buckets system but without grit guard)

2 - full car claying with "3M-Clay Bar" with water+car shampoo mix lubrication on the first day only (using micro fiber cloth to wipe dry)

3 - polishing with "Soft99 Luster Cleaner+Polish" (using china made polishing machine on big areas and hand power on edges/small areas with sponge and buff off with micro fiber cloth)

4 - waxing with "Turtle Wax-T123 Wax" - 3 layers on front bonnet, 2 layers on roof + both front doors and one layer on the rest of the car (using hand applying with sponge and buff off with micro fiber cloth)

5 - i still have one new bottle each of "Waxco-Carnuaba Wax" and "Turtle Wax-Ice Speed Compound" haven't tried on my car yet......how or when should i should  use this on cars?

- claying with "3M-Clay Bar" on my car doesn't really pull out any impurities/dirt from my car's paint even after running many many time, did i do this right?

- i find using "Soft99-Luster Cleaner+Polish" really can clean my car's surface really well but heard that this is too abrasive to the car paint, so i might only use this 3 or 4 times in a year.

- first time using hand held polishing machine, having problem with the device as it need really firm hold (if not it seems to jump around a lot and pulled to one side...........need to get used to this device) then using my hand which i have more control but tiring

- waxing with "Turtle Wax-T123 Wax" seems so easy and fast on my car's paint, i can actually spread this wax on my whole car first then only wipe it off.

- i use to polished with "Soft99-Luster Cleaner+Polish" and waxed with "Turtle Wax-Super Hard Shell" on my other car (saga BLM - solid white, 8years old original factory paint) and the result is way much better and shinier then my metallic silver color car, any reason on this?.....or need different methods to do detailing between metallic silver paint and solid white paint?

- any advice on how to removed water mark stain on my windscreen.......using any of the products that i have as above?

sorry for this long story.......old-man learner here, interested in doing my own cars detailing as a form of exercise for me too but feel shy because of using cheap and simple products and tools.......hopefully some sifu here can guide and provide advice to me.........thanks a million, cheers.
