Thanks! Will take a look

Is it easy to apply carpro coating? Thinking of buying from shopee and diy instead

My advice watch a video thru YouTube first for a guide and tips

Anyone got recommendations for acid car wash?
For monthly usage due to park outdoor waterspot.

Carpros descale bit expensive
Kcx reactivation decent price, jz looking for alternatives

Using acid car shampoo for waterspot monthly is a bit extreme, also you dont mean those black lines right? it's the rain spot marks, right?

I'd say prevention is better than cure : I'd recommend using a decent spray sealant to protect & prevent stubborn waterspots rather than using acid car shampoo monthly.

Thing is nearby got condo in construction, dust combine with morning dew anyhow also will have beads form into waterspot.

Also need to reactivate my coating, so might as well lol. See how it goes , if less rain maybe jz 2 month once. These 2 are coating safe also, jz checking are there any similar option out there

Maybe try spraying away the morning dew before moving the car?

I see. In the market currently these are the only 2 acidic car shampoo.

There is another option which is to use the common "Watermark Remover" product out there, it's much more affordable but it has it's risks as they are usually quite strong acid, you need to know what you're doing with it.

I still do strongly recommend aapply spray sealant on your coated car afterwards, it does help reduce stubborn waterspots and stains.

Any intro for spray sealant?

I tend to use more osren products so I'll recommend their paintwork coat / Hydro Ceramic Shield, but similar products from any reputable brands should work fine as well.

regarding using 'watermark remover' products on coated car, you can refer to this Youtube video, hope this helps.

Can consider rhino watermark remover, I used mthly on cars parked outside 24/7 although car is ceramic coated with china brand and maintained with armor ceramic spray

Sorry to bump a reply from so long ago. I believe what you had is road grime/dirt bonded to your paint/sealant, unfortunately it’s very obvious on light coloured cars, not restricted to white cars only.

From your photo looked like there were some high and low spots of the Fusso coat since it does not appear exactly like normal watermarks etching. I had similar issue before with some wax as well, got most of it out by using a clay bar. Removing it by polishing works too, but may not be the best method as one should always start with least aggressive method. Some may argue must polish after claying since that install swirls and marring too, depends on the assessment of the detailer, ymmv.

There are quite a few “ceramic” sealants or sprays that can last 1-2 months easily and have comparable water beading behaviour like fusso coat in the market now. Perhaps you can try, and can’t avoid routine wash for light coloured cars, it’s a lifestyle

you are right. its just road grime that has caked up. i just wonder if other cars also have difficulty in cleaning them if left too long like maybe only 2 weeks? I can understand if left like a month or more but two weeks seems a short time. mine wont come out with just normal car wash but now I found that with some non-abrasive polishing liquid, it will come out. Thanks for your input

Our weather is quite harsh at times, raining for awhile and hot sun right after. Water spots get baked on immediately, also depending on where you use your car mostly, if industrial area then it’s worse. Happened to my car too as it’s almost outdoors 24/7, just different pattern due to the water behaviour from product used.

Also possible to be a fusso coat issue, not unheard of, perhaps try other sealants as suggested by other members above. Continue to wash periodically and clay it perhaps once a year/when necessary. It’s not easy to have a light coloured car in tip top shape all year round.

just got my new car, about 1 week old now.
is it okay to apply coating without clay and polish?

clay and polish is to prep the body, in english to clean the body of contamination and smoothness. Its like before applying lotion to your body you scrub and take a shower.

hence its an important process, else you will be coating with all the dirt on it.

Not ok.

The coating needs to bond with the paint and if there's a layer of contaminants in between the paint and the coating, it won't last.

Looking for a normal car wash shampoo for my car. Saw this from Soft99, seems quite cheap. Shall I go with the yellow one? Any disadvantages if compare with the blue one?

Or any other better alternatives at this price range?



Thanks
