oh yes if you've seen my previous posts, i'm a huge fan of BSD

not a fan of their new distributor pricing though, easily 2-3 times from what it used to cost.

Looking forward to your feedback on those Vietnam ones!

no such issue for me

key is to keep the windscreen and the wiper blade clean.
time to time (maybe bi weekly or monthly, or every time there is fallout such as bird droppings or situations where the wipers gone through more dirt) i will use either IPA or Megs UQD to clean my wiper blades. (windscreen too if there's fall outs such as bird droppings)

my rain x washer fluid additive mixed with any other cleaning washer fluid additives will maintain windscreen cleanliness and rainx effectiveness and last practically forever since it continually replenishes rainx

i only have silicone wipers.
sometimes they do stick/judder once in a blue moon, like you said when dry, if it ever happens, i just need to spray washer fluid, and problem instantly gone.
that's provided i even need to use wipers lol (maybe very light rain and traffic jam can't get speeds above 40kph i guess)

consider adding meguiar Ultimate liquid wax or any of their latest LSP products.
UQW is very weak as a LSP and maybe last 1-2 weeks, a month or 2 if you're lucky/parked in shade rarely any rain etc.

personally, i gotten them as a bundled last time restocking their UQD, and i dont waste my products so happily using it as a drying aid.
so far so good and left maybe 60-70% after 1 wash session on 2 cars which i have also reviewed and written about meguiar's ultimate all wheel cleaner.

context!
but for the tldr folks, skip to the conclusion portion.

waxes (as some may say outdated ) or any LSP will HELP the clear coat and the clear coat will in turn help protecting the car from UV
also, if you've driven a well detailed car over the high way or any roads under hot sunny day, and notice the road signs blinded by your car... how much sunlight/uv is your car absorbing, when they are actually REFLECTED OFF your car?

food for thought! (though sometimes try not to overthink too much, or fixate onto UV lol.)

I'm on PIAA and normal cheap brand less silicone also no issue lol

So it isn't all (I'm not affected), and I don't think UV rays have anything to do with this issue lol

Definitely not necessary, especially if your objective is for fallout such as bird droppings

I don't personally use foam lance though, cuz lazy since it'll be one more extra step lol!

You're welcome!
Yeah I use a 110 Karcher K1 Or was it K2 lol, made in Germany but it's now leaking/losing pressure so it'll keep "activating" to maintain pressure even if you're not pulling the trigger lol

Here's the thing if you want the foam lance to really be effective: on step 2, after foaming and maybe soaking in foam a bit, you need to pressure washer rinse once, then still doing the classic 2 (or more) bucket wash to be really effective on dirt. (Or wash and wax lazy cleaning, lol)

If you're lazy and just do foam lance then just scrub those foam and rinse after, ending the session, you're not very different than majority of outside cheap washes right? (Not that it's wrong, I personally do cheap outside washes too lol! So long their detergent/shampoo doesn't eat through my wax lol)
It is convenient if you're not into the detailing part of things.

However if you are, then step 2 is one extra step, and for lazy, why would you add another step

Usage and wear and tear kot
Been using maybe since 2012 or earlier? Lol
Not really usage issue I don't think.

Also, doesn't take mud to have road film etched into your clear coat.

Any cars without cat, diesel trucks, bikes especially the 2 stroke ones, can easily dirty up your car and probably make it worse than mud that can be easily pressure washer washed off lol

I used to detail my Iswara and later on Inspira similarly.
I actually detail my current car less than my Inspira lol
So I personally don't think the car matters.
It's how much you want to take care of it, or how much you love it

Well, you just gotta find proper wash centers.
You know well there's actually proper places that charge hundreds of not thousands for a wash? Whether you willing to pay or not is another matter, my point is those guys won't have questionable rags lol.

Also, there's places with reasonable price that also went have questionable rags la... Like gloss tech at Melaka, under RM15/20 can have a good wash.
But it's Melaka la
I'm very sure KL SEL also got similar places at similar prices

Honestly not a whole lot of difference.

From detailing perspective, it's another layer of contactless wash to further minimize dirt scratching the paint (or more accurately clear coat) surfaces.

From convenience perspective, you don't need any buckets, simply foam on agitate said foam a bit, rinse off, very fast! (Like outside wash shops)
but you see not rinsing and cleaning your wash medium, be it mitts or sponges, introduces risk of dirt scratching around your paint.
If you still have buckets to rinse and then reapply shampoo (increase lubricity on the wash medium) then why even foam lance?
We Go back to the first example I mentioned earlier right?

Don't even need to think so far about the foam lance density and lubricity already

I'm probably the only old school left here that still using old school boutique waxes

And since they so hard to finish on my annual detailing session, which wax protection also lasts a whole year, very reluctant to change/get new product(s)

If younger a bit and single, and not hooked onto Motorsports, maybe still chase geh

Now married everything changed
Seller want to hepi also need to pass wife stage

1) wrapping is another layer, be it ppf or vinyl or other materials wrapping over existing paint
2) coating is a very thin protective layer (aka LSP or last step protection) on top of your car original paint. think of it as a very durable wax
3) yes, reputable /good wraps full car begin 2-3k+ 3M or Oracle wraps easily over 3k and those fancy types will be well over that. repainting your car may be cheaper.

yes protect ori paint
yes and no on lower maintenance. because neglected wraps will require replacement, and replacing wraps are akin to re spraying your car. technically it could be more difficult to maintain wraps as they do not have similar hydrophobic properties of well maintained and protected (LSP, such as wax/coating etc) cars. eg: dirt / bird droppings will directly cling on your wrap as opposed to having a slick clear coat.

yes your feeling is correct.
people do coating because they appreciate their original car paint/and gloss
PPF / vinyl / any wraps will never give you that satisfaction.

think of screen protectors and bare naked glass on your smartphone.

also, some people go for fancy wraps that paint jobs may not be able to offer.
eg: special chrome, rainbow, gold, carbon fiber, etc.
or, Matte wrap that do not have to worry about surface protection and maintenance. a matte paint finish could be very difficult to main pristine condition vs a clear coat/glossy paint surface.

i personally disagree that rain water is better, ESPECIALLY in the city center like KL.
polluted rain can easily be worse than filtered (those huge tanks placed outside that most households SHOULD have these days) tap water.

i'm still using... my gel from maybe 10 years ago still cannot finish, cannot move on to new products. haiyaa

You'd be surprised how your body panels contain fall outs that can yes, have iron as well (look up decon steps in detailing)

Putting this to action again on a new car.
And renewing existing HRV glass hydrophobic Acton.

I'm using on windscreens too, and lasts permanently because I also use RainX washer fluid additive.

It helps lube up silicone wipers too

I would say yes and no

No because it's generally a diluted rain X that doesn't haze up

Yes because it's mainly alcohol/solvent/oil based that it'll either allow easier wiper to rub off any road film and bugs, and that's provided they are even able to cling on a RainX treated windscreen, especially most of the time I don't even need to use wipers to begin with lol
