we actually testing the products recently. will do a write up soon.

youtube videos and information within the v1/v2 and this very v3 thread will suffice.

and yes if you mean JUST the waxing step.
however preparation is equally, if not even more important than the waxing step itself.

Without making it too complicated for you, I would suggest trying out what we call an AIO (All In One) instead. An AIO have stronger cleaning property so that it would clean off those stubborn contaminant that normal wash can't remove. It'll also lay down a layer of protection while doing it. Duragloss Marine Polish 501 or the Polish Cleaner 101 are good and the protection can last for a month or so, longer if you're using a topper. There are also other AIOs but I have not much experience with them so I leave to other people to recommend.

what happens is that your wax/LSP (last step protection) durability is severely reduced. if you wax every week (eg: spray waxes) then it shouldn't be a problem.

and, it just doesn't feel nice sealing all the contaminants/defects under wax/LSP (you want your car condition to be tiptop/shiny shiny, no?)

A few possibilities:

1. For the paint itself - contaminant *could* possibly accelerate oxidation or failure of the clear coat. But this would take several years of neglect in order for it to happen.

2. For the wax/sealant - waxes/sealants adhere best on clean surface. So, if there's any contaminant, adhesion would be weaker and this would result in shorter durability or cloudy patches after application.

If you're really worried about it, then there's only one thing you should concentrate on - WASH REGULARLY. Most shampoo would leave a tiny little amount of wax/sealant. Though not enough to give proper protection, at least it's something and the surface would stay relatively clean hence minimizing contaminants to cause maximum damage.

Furthermore, most of the normal consumer range waxes/sealants also contain some cleaners in them. Taking that into consideration, the process of applying waxes/sealants of any kind would also remove *some* contaminant due to the cleaner in them and also the aggressiveness of the applicator (you'd normally see the applicator turns dirty during/after use).

Shucks...now it's getting more and more complicated. Well....if you regularly clean your car and occasionally wax it...don't worry la...most probably the car would have left you before the paint is damaged.....

Wash car, followed by wax is actually okay. The additional steps such as claying, polishing, and even IPA wipe, are just to provide the best surface to achieve the optimum bonding of wax on the paint surface. These steps are basically surface preparation.

Without proper surface preparation, you still can wax your car after car wash. Wax will still be there, no worries. The only thing is about the durability of the wax on the paint surface. That's it

Well...just to comfort you....washing a car without a wax on every week is better than having a wax on but washing the car once a month.

You don't really have/need to wax the car every 2 weeks. A good quality wax should be able to provide good protection for months (or at least one month). Concentrate on MAINTENANCE - wash and topping up with some spray topper/booster. I've been doing it for ages and the only portion of my car(s) paint that are damaged are only those caused by inconsiderate *so-called* human beings or accidents....

ps. when I was using waxes/sealants, I only do a 'proper' detail - i.e. light polishing and re-waxing, maybe once in three or four months....

Spray topper, example of them are like Meguiars Ultimate Quick Wax, Optimum Car Wax, Mothers FX Spray Wax, TurtleWax Wax-It-Wet, 3M Quick Spray Wax, Duraglos Aquawax, Autoglym Aqua Wax, Sonax Brilliant Shine Detailer...just to name a few (that I've used and tried). The ones I mentioned are all from the more established and reliable brands and available in Malaysia. Google them and learn what they are and what they do. Personally, for a black car, I would recommend Sonax Brilliant Shine Detailer if you're looking for durability or Meguiars Ultimate Quick Wax if you're looking for the look. If for ease of application with minimum risk of cloudy patches it's the DG Aquawax. Pair the spray waxes with a good regime and regular washing, you might not need to wax your car for months. Try one of them and...errr...*ehem* the Sonax Brilliant Shine Detailer is on sale at Sonax HQ, provided that it hasn't being 'scooped' by the kakis here already...check out their fb page....

Yes. The Sonax BSD is for application after wax or after wash on top of existing wax/sealant, not a substitute for one. It can be use as such but the protection wouldn't be as good as a proper one...still good but just not as good.

Not just an additional step to enhance the look, these spray waxes are also meant for MAINTENANCE. Using it will stretch the durability of the underlaying wax/sealant so you don't have to re-apply them frequently.

Don't know about SGCB's products as haven't tried them before. But so far most spray waxes are quite compatible with other waxes/sealants from different brands. I have a few spray waxes and waxes/sealants and so far I haven't had any major issues in term of compatibility.

From the description, it looks like a syntactic sealant, no canuaba was mention. I don't understand the last sentence of "suitable for imported car, luxury paint".
I haven't use any SGCB product before, but if it is just sealant than you can look at Meguiar’s #21 Synthetic Sealant 2.0, Collinitr 476. I'm using 476 with aqua wax or ocwax as topper/booster/spray wax. You can omit the topper if you think is too much work.

(Out of topic) I think the effect of SGCB coating wax looks appealing to me. Just not sure about its durability.

Haha, actually it's not that complicated. Just a spray wax. Provide a quicker way to wax only. Also, to top-up wax on the current paint surface. 

You like paste better? Liquid is usually easier to apply. If using DA machine to polish, liquid is easier to apply. With paste, you need to spread it with something like a butter knife to the foam pad of the DA.

Anyway throughout the years, kept buying other stuff and found it better like Meguiars' M16 paste wax. I started collecting other paste wax like 3M Perfect It and Meguiars Ultimate Paste Wax. I like the Meguiars Ultimate Paste Wax. Easy to apply and buff off like liquid and looked very good on black cars. But cannot remember off hand how durable it was. I also bought liquid type wax like M26 Hi-Tech Yellow Wax and Meguiars Gold Class Carnauba Wax which I quite like but does not last long.

In my honest opinion, a spray wax / quick detailing type of application suits you better. It's more straight forward and easier to apply after a wash then putting a layer of conventional wax.

quik wax is ALREADY a spray topper

and yes, very brainless/no effort application

spray/wipe on, most people wipe off, i don't even f***ing bother. (not wiping off)
