I have recently noticed that water leaks and settles on my car floor (Highlander) anytime it rains heavy(like yesterday). I have checked the sky roof and carrier-holds for any sign of cracks, but can't find any. Makes the car smell terrible and takes at least a week of hut sun to dry again. Can anyone profer solution, please?

Buy a transparent car cover and drive in it whenever it is raining.

Do ur car has a sun roof window? If yes, it's the sun roof window that is leaking. Some panel may request u to block the window parmanently. But we can get if resolve without blocking the window.

If the size of a molecule is in the range of 10 raised to power minus 7 why do you think you can find crack with your naked eye?

You know where Jiji is?

Good.

That's all the info you need

How please

Take your car to a good panel beater. He can use this black gum in long white container to seal it for you. If you are in Abuja, I will refer you to my panel beater, I can assure you it will be solved.
