Many thanks for the advice

I use Rainx and face similar misting issue that usually occurs on cold mornings. Usually I have no choice but to spray wiper fluid and wipe off the mist with wiper.

No idea why that happens. Can't tell whether I 'overcoat' it or not. My situation is such that I can't let it cure for 1 day. At most is half a day.

So I just live with it. This is a small inconvenience compare to not coating it and kena waterspot issues later.

Thanks for the suggestion, but might not be suitable for this case as the product says is for interior glass but the mist forms on exterior glass. Weird right?

I think C.W.S intention is to clean off iron particles from windscreen without removing the windscreen coating is it?

Maybe you can try ask him, haha. I am sure he will appreciate if you notice his workmanship. Speaking of which you reminded me I didn't try whether carpro PERL have water beading effect or not. test it next time. Hehe

I use Meguairs NXT car shampoo. A bit expensive but I quite like it, good foam and cleaning ability in my opinion.

Noticed today Carpro PERL on tires does still have a bit of water beading / sheeting effect even after 2 weeks. But not so much on external plastic parts.




Also, noticed my parents' car have the same problem as Victor. There were also some other bugs and flies all died inside. Wonder how they get in? Hmm..

Bro Clement, I think basically if you wash your car regularly (once per week or at least once every 2 weeks) you dont need to worry too much about watermark. Watermark are usually a problem only if water dried on your car and you leave it without washing it off for long period of time and the mineral deposits in the water is baked or etched into car paint / window.

Another thing I would suggest you to do for your new car, is get coating for all your car windows (something like rainx), this in my opinion helps to minimize potential watermark on your window (though it may cause wiper juddering).

I see, maybe you can consider trying rainx since it's not too expensive I think. I also sometimes get morning mist on windscreen. Couldn't find reason why it happens so I just spray water and activate wiper to get rid of it.

Application : easy, after diluting it just drip some on cloth / sponge that wipe it on rubber/plastic/tire. Best thing is you don't need a lot, like 1 or 2 drip on sponge is enough for an entire plastic door panel. Just need to spread a very thin layer of it.

Durability : honest don't know long term durability because I just started using 3 weeks ago. Based on observation, on tire still have water beading effect after 2 weeks but the matte look has faded. Internal plastic still looks good after 2 weeks. External plastic seems to have faded after 2 weeks.

Protection : still can't tell if it really helps prolong life of plastic & rubber against the sun since I only started using this 3 weeks ago. But this product does say it provide protection against UV rays.

I think carpro perl is worth a try and indeed very versatile. It's especially nice in car internal plastic panels. Makes it matte and a bit shiny.

Since my car is parked outdoors all day everyday so I spray wax my car almost every week and maybe cleaner wax once a month. I have not yet start claying my car yet though.

I would think of it this way :
-any loose dirt would already been wash off before waxing
-paint might still have embedded dirt that requires claying
-however when I wax it, as long as I don't use too much force, those embedded dirt won't come off, stick to sponge and scratch car.

Embedded dirt is also why I use cleaner wax once a month as it helps to remove some of them. The above is just my opinion. Feel free to experiment and share your thoughts.

Bro, u need cleaner wax for those stain. I would suggest u get soft99 meta clean.

Edit : another alternative would be APC (all purpose cleaner).

1.nope. Film is a physical object wrapped on car, coating is something like harden liquid on car surface. Most would say film offers more protection than coating.
2.no idea.
3.no idea.
4.not a good idea. They will probably scratch up your film / coating / paint badly with improper washing techniques and dirty cloths. Better to wash yourself or find a good detailer.

Not trying to burst ur bubble but maybe you can try opening a new thread on main page to ask Coz most of us here is more towards the good old fashion wash, polish & wax method. Just a suggestion

Mind sharing how is Osren Tar remover like? And how do you use it? Spray on paint and wipe?

Reason I am asking is Coz I bought turtlewax bug & tar remover in spray bottle. I tried using it and found I don't like it Coz it's very oily. So I wonder how are other brand of tar removers like.

Can I ask what do you mean by using tar remover by machine? Like spray it and use DA polisher to spread it? So far I only spray and wipe off with cloth.

I see. Thanks for sharing

Is it coming soon? I am quite curious whether this can withstand Malaysia's hot weather or not. I also guess this ain't going to be cheap. Maybe around RM80 to RM100 per spray bottle?

I see. Thanks for sharing. I really hope this new product can withstand our weather, if it does I would buy it in a heart beat (provided it's not priced too ridiculous )

You can get it at Osren HQ at Kepong, you can Google the address. If not you can find other brands of Tar remover at various Ace hardware outlets too.
