preferably to purchase over counter, maybe eneos or ace hardware
acceptable with any brand but ease to purchase
what is the brand have full range from claying till sealing?
anyway, i looking the product which serve the only purpose, clay means clay only, wax means wax only some sort... Meaning not looking for those all in one (wash + polish + wax) products

From your posts, sounds like you've already done quite some readings and have a good understanding of what you're looking for. In your case, let me suggest a mix of brands instead of only sticking with one. Reason being, I don't think there's one single brand that excel in everything. I'm also going for the assumption that you intend to use the products by hand (with future upgrading to a DA/ROB).
1. Clay - Soft99 Clay bar. Try to get the one for White color car. Or if you're willing to spend a little more, get the 3M clay - blue colour in a black tub/container.
2. Compound & Polish - I suggest the Megs twin Ultimate Compound and Ultimate Polish. These two would be able to tackle *almost* any defects.
3. Sealant - now this is the tricky part. For OTC I would suggest 3M Perfect-it Show Car Paste Wax. But if you're wiling to make an exemption, I strongly suggest getting Duragloss 105 Total Performance Polish. There are a couple of shops around PJ area that sells them. You can find them at Duragloss Malaysia Web.
Oh...and after all the above, I do need to stress that THE MOST important part in detailing is actually MAINTENANCE. There's really no point in spending all your time and money doing up your car to shine to your expectations and then getting it all swirled up again after one (or two) washes. You should find yourself a good quality shampoo, wash mitt and, most importantly, drying cloth, and study the proper washing and drying techniques. With good maintenance, chances are, you won't need to do a full detail job for quite a few months.
Regards.

I have a question krismas and I hope you don't mind. Is there any place that I can buy optimum instead of online? Thanks.

I'm not sure how they operate, but you *might* be able to get them at Optimum Malaysia authorised dealer/distributor's place. Other than that, I don't know any place that sells them off the shelves.
