Hello Mike,
My colour of my car is sapphire black and there are some swirls + minor water spots. Also, the paint on the bonnet and front bumper is about 2 wks old as they have just been replaced. I suppose its not safe to apply a wax on it yet?
Most paint manufactures recommend between 30 to 90 days to pass before you apply any type of product whose purpose it to protect the paint by coating over and creating a protective barrier-film. This would include most waxes and paint protectants no matter what they are called.
I will be using a Black & Decker WP900 orbital polisher and here are my
questions
1) Will Meguiar’s speed glaze be able to remove swirls and minor water
spots?
This will depend on the hardness of your paint, in other words, how hard it is to abrade, or remove small particles of it in an effort to level, or flatten out the finish. It will also depend upon your application material, time, heat and pressure. Because these are all variables that only you will know, I cannot give you a blanket, yes or no answer.
Typically, the orbital style polishers like the one you mention above are less effective at removing swirls an water etchings than rotary buffers and smaller polishers like the Porter Cable Dual Action Polisher. That’s because of their lager pad size which dissipates pressure over a larger area making it less effective at removing paint, and typically slower OPM’s, Oscillations Per Minute.
But… you never know what you can do until you try. If it were me, I would give it a try with either the #80 Speed Glaze, or the #83 Dual Action Cleaner Polish. The #83 is more aggressive than the #80. With a polisher like yours, if you take your time, you should be able to get good results. I would definitely test your product choice and your polisher in one area first to test it’s ability and dial in a system of how long to buff, how much pressure to use. After working one area, apply your next products, (polish or wax), after removing the cleaner/polish and then inspect. If it looks good, then repeat your process to the rest of the car. If it doesn’t, then you will have to improve the process.

2) Is it safe to use speed glaze on 2 weeks old paint? Will it provide
protection for the fresh paint?
Yes it is completely safe to use Speed Glaze on fresh paint. You can apply any of the 80’s series to paint as soon as it becomes
dust-free, that is when dust lands on the fresh paint it will not stick to the paint. One day after painting is a pretty good standard unless you using some of the new paints that set-up in 45 minutes or so, or if you using a slow solvent evaporation paint then a day or two. Speed Glaze does contain a special
Paintable Polymer that is safe for fresh paint and adds some protection. Not as much protection as a regular coating of wax, but more protection than most other body shop safe type glazes and polishes.
3) I plan to apply Meguiar’s #16 (except the bonnet and front
bumper) after using speed glaze, what do you think of this combo?
That should provide you with an awesome looking finish. #16 adds a lot of gloss to finish that is properly prepared.
I live in Singapore and temps here are about 33-36 degrees
Celsius with high humidity and occasional heavy showers.
Thank you for your time and for reading this. 
I love helping people get the best results from their time, money and efforts. Good luck, and if you have any further questions, please feel free to post back here.
Mike
