nothing special

I use small piece of tissue/toilet paper or kitchen towel to apply...don't use too much... after hazing...wipe haze away with damp cloth

redo as required or when feel like it ...

I no experience with daily hot sun...

if just wanna see clearer in the rain... can just use rainx

rainx has high alcohol will clean out slight oil film...but won't clean water spots

if want virgin spotless glass...then must clean out water spots first... I use autosol metal polish...then wash away residue oil with dish liquid... then apply rainx

cleaned with autosol metal polish with a small piece of rag... wash with degreaser to remove the polish oil...then rainx

no scratches from the polish...watermark all gone

fyi...rear windscreen exposed to rain n sun

no idea what's in cif, zip, etc... probably baking soda based abrasive... don't try vim I think uses silica sand will scratch glass... theses are mechanical methods, i.e., scratch/rub the watermarks off

metal polish probably got stuff that reacts with oxidations and minerals, either dissolving some and making other "softer" before it's abrasive rubs it off. don't use autosol on paint/plastic chrome it will scratch

that extreme shield wax is "grippy" feel type after application...as you apply the polymer gives up water... very weird when i first try it long time ago... haha

totally opposite the feel spectrum from Carnauba wax...hahaha... its like sonax polymer net shield

its a different type of product...good at controlling dust attraction...if lazy to wash car, car stays "cleaner" between wash or wash less frequent...but these were developed long before cheap spray coatings...these coatings does quite a good job now imho

carnauba=0, sio2=10...this 7~8 for repelling dust

btw...needs a lot for a car, i don't recommend buying now...many many yrs ago, this and the amourall wheel protectant the two best product worth getting for dust control

eh...wrong liao... that grippy layer supposed to stay on... you just gently wipe off any excess and water... like I said this product is 180 degree opposite of wax... hahaha

extreme shield wax is lsp

speed bead is a quick detailer... you use these for cleaning & touching up between waxing

coating is not a necessity... people do it because super nice beading, easier to wash, stays clean longer...

yes... the grippy feel is the polymer layer that just got bonded to the paint

no difference...all refer to same class of chemical, normally sio2 but got others as well, and also different carriers

anyway I'm not into coating, my resolution is to finish what I have...hahaha, but am happy to try out those 9h rm5 per bottle stuff...

it depends on you ah...

coating is very different... I got a car on coating... so easy to wash/clean...stays clean for very long... just wash n dry...

polish/wax need more work/effort... but easy to try out different products... always got new things to try... haha

both types give different kinds of joy...

tbh...if I get a new car...I will diy coating... because the paint still nice n clean so doesn't need much prep work... alternatively can try those cheaper diy spray on wet activated coatings...

anyways no hard n fast rules... you do what is best for yourself

once you coat... polish/wax don't stick anymore... haha

maintenance is those spray coating

imho...send to shop pay a few k not worth for new car... the product is quite cheap... majority of the cost is in the workmanship for paint correction, etc...

instead i would consider trying those new hybrid wax stuff... I can still give up, surrender and send for coating later... hahaha.... start with lower cost stuff first and move upwards...

you can try using autosol metal polish... I showed this few weeks back... search for my post here...

front, rear, windows...all glass surfaces I've used... but yes test small patch to see and gain confidence...
