Good to know that you find our thread and knowledge worthy enough of the appreciation, i really am glad. 
Definitely next time it would be in good light, usually in summers it is difficult to meet in broad daylight because of the excessive heat, our latest meet was in good light as well, but not under the bright sun.
But next time inshALLAh when you come we would make sure you get what you desire sir.
For regular use i would advise you to invest in either Meguiar's Gold Class 2000-2500 rupees, or Mothers California Gold 1500-1800 rupees.
Both are carnauba waxes and are great, but i rate Gold Class a notch above California Gold.
If you wish to buy a synthetic wax then Meguiar's NXT wax, same as the price of Gold Class, but would give a little more protection against rain and dust than gold class, and would keep intact with your car for a little longer, BUT wont have the depth and gloss of Gold Class.
For interior spray, STP son of a Gun, excellent product for the price, cleans and protects, if you wish to get something even better then Meguiar's interior detailer spray or wipes.
