Munpeng, Diamond Cut is not a Meguiar's consumer item. Thta's why you can't find it at any shops, you have to go to Hypercoat ( nearby Regalia Busniess Centre, Subang ) for 'em. U can try Scratch X instead ( btw, u have to use a dual orbiter machine in order to use Diamond Cut effectively ). Scratch X is Meguiar's answer for normal users who wants to reduce or eliminate fine swirls and light scratches by hand work.
How to use Scratch X : Always wash, clean and dry the areas which you want to apply Scratch X first. Use a foam applicator pad / or microfibre pad ( Meguiar's have both items, the foam applicator pad at RM 6.00 each, the microfibre pad at RM 22.00 per pair, but local Meguiar's prices have been increased on the 1st of June though ), and put a small amount of Scratch X ( a 20 sen size amount is OK for starters ) on 'em. Apply the Scratch X to the areas which you want to treat thoroughly 1st, then work the Scratch X in! You'll have to spend some elbow grease here. Scratch X have diminishing properties, so as you work in the products ( not so aggrasive, but with passion! Means that you have to put some extra work lah, not like applying or buffing wax ya. )
the product will start to haze and will dissipate. When it is almost gone ( it starts to haze, as in the applied areas are now almost clear ) buff it off with a microfibre cloth. You have to repeat the steps above for at least 3 times, then take a good look at your work. I can promise u, if you cannot clear off the fine swirls / light scratches, at least it will be greatly reduced ( I can promise you that because I'm using it! ) But be prepared though, if you want to work your whole car, it'll be impossible to it in a day, because you'll be soooo tired... For example, the front bonnet can take from 45 minutes to one hour plus, then front fenders can take up to 45 minutes each panel ( total 90 minutes / 1 hour and a half for both fenders ), front bumper another 45 minutes or so, so in total, to do a Scratch X work on a whole front end will take you at least 3 hours ++ minimum. My arms and fingers was so tired after only treating Scratch X to my front bonnet, so you can imagine how much work is required to do so.
If you do not want to have tired arms and hands, there is an alternative. Go and get yourself a Bosch GEX-270AE ( last time was RM 300++ ) dual orbiter machine. Then drive off to Hypercoat and get some Meguiar's backing plates, buffers and applicators, a total of around RM 300++. You can use this machine to apply and buff off the whole car easily. Remember to tape off rubber trims etc ( to avoid products to stick to 'em! ) and also windows ( use newspaper lah, to avoid product sling ). But with a dual orbiter, u cannot use Scratch X. U have to buy M80 Speed Glaze, and use that with the dual orbiter. Although the costs to use a machine, the correct products etc will cost you about RM 800++, you get to save time and these products lasts quite a while too!
You guys might think that I'm promoting Meguiar's stuffs too much, but they works! And the forum (
http://www.meguiarsonline.com is a haven for all things Meguiar's. They take the pains to educate customers on how to use their products properly.
I've used a number of other detailing products on sale here in Malaysia, and most of them are not working good enough, or is working way too much ( adding more scratches after application! ). Meguiar's stuffs works well ( if you know how to use 'em properly ), although the prices is getting a bit expensive nowadays.
If you guys are interested in purchasing Meguiar's consumer items, it's on sale ( with a SIZABLE discount, over at KLIMS. Discount is 10% for purchases under RM 100, 15% for RM 101.00 - RM 202.00, all the up to 35% for purchases over RM 501.00! Damn good deal ( and I splurged over RM 300.00 worth of MG's items! hehehe )
