My answer to some of your questions:

1) cleaner wax is generally less used for protection purposes and more used for cleaning purposes. Perhaps it would be better for u to get a synthetic wax such as fusso coat for durability, since u do park your car outside all day every day.

2) claying shouldnt be taken as a regular activity, as usually ppl clay to remove contaminants that cant be washed off prior to polishing. Also, Meguiars Quik Detailer isnt the most cost effective option as clay lube, u may be better off trying out using ONR as your clay lube instead. Whether to use a wash shampoo as clay lube depends on your claybar, as I have seen some claybar doesnt work well with wash shampoos as clay lube.

3) Carpro PERL is commonly recommended because it is dilutable, therefore making it highly cost effective. If u are not going to be the type to apply trim and plastic protectant frequently, then even Meguiars Protectant can work just fine.

4) Hmm, I have a mixed understanding on this. While there could be some possibility regarding the release of oils from exposed plastics, there are also other factors such as the air in the car while driving, as well as if u use any perfume scents in your car. With that said however, I dont think his method is necessary if u just regularly wipe down all your windows with a damp microfiber towel during each of your car wash session. The glass cleaner would only become necessary after long periods of no wiping down interior glass. Glass cleaner doesnt affect window tint, however please dont use that rough sponge he used for scrubbing the glass, as that sponge would almost certainly scratch your tinting.

Hope this helps.

cleaner wax is more for cleaning purposes. whereas dedicated wax is a wax dedicated to shine and protect.

if you are using clay cloth or synthetic type of clay, i recommend shampoo. if clay bar, use onr diluted or quick detailer.

plastic and rubber you can use any oil or water based type gloss enhancer. oil would last longer but would stain. water wouldnt stain that bad but wouldn't last. this is my understanding based on product formulation. i usually use oil type like meguiars endurance, but will buff excess with a dry m/f. it helps to prevent black streaks.

The recommendation is always to apply the stronger and more durable protection such as synthetic wax or sealant as base protection, then weaker protection like carnauba wax or spray wax as top sacrificial layer. The base protection grips on the paint longer, and u just need to topup with weaker protection regularly.

For Carpro Perl, I only have 1 dilution mixed and i use that for all surfaces. No sense having many bottles of the same product in different dilution when the base priority is just protection. Thats my 2 sen.

for me
1 dilution one spray bottle

I'm thinking to purchase Meguiar's , but i'm not sure where to start ...compound , polish , wax ???? Any starter pack & advice ????

Can wax or sealant protect swirl marks or scratches? It suppose to be a layer of proctetion right?

can i ask wax cleaner AKA AIO.. is this consider polish? how often can it be used?

Ok after i applied sealant on the car, and after the first car wash the car is not that shine from first time when just applied sealant. Should i add a layer of quick wax or quick shine detailer?

Any quick wax to introduce?

new toy!!!

Can share link to purchase??

Thanks, have you tried the product before? Is it effective?
I found Lazada is selling RM98 for 1 Litre... still thinking to invest on it or not.
I wash my car 1-2 weeks once.
Recently start seeing water mark on the car (must be due to always rains these few days)
After washing and drying, the marks are still there.
How do you guys avoid water marks other than washing regularly? Does wax frequently will help?
My friend ask me always wipe the car after raining 

70/30 or you could check out forensic detailing channel for other opinion. It's always easier and convenient to use carpro eraser or similar products to prep the surface for wax, coating.

V429 Agree on the above...it all depends how much perfection you want...there is no right or wrong, it depends on individual, if we are tight on budget, just go with dishwasher...which I had been doing for ages.

Only recently, (ada duit sikit la), so spend on Tar remover...I just dont like IPA....

just my 23 cents 

Lol, welcome to the club! I think many of us over the years of detailing may have bought, tried, didnt like it or it didnt work as hoped, then kept it until too old and eventually donated or threw stuff away. Guess its all part and parcel of learning what works for u and what doesnt.
