Because I have to leave the second car outside in the sun I bought a windscreen sun deflector, the type that has two flaps that tuck either side into the front doors.

I found out the hard way that after the heavy rain the other night, that those flaps allow water to enter the car. This caused the carpets on both sides to get saturated.

Now have both doors open and a fan blowing to try and dry out the interior and getvrid of the musty smell.

Those sun deflectors should be sold with a warning.

I find the internal ones are too difficult to install, they tend to fall over, but after the mishap with the exterior one I have no choice.

Anchor the internal ones with the visors and behind the rear view mirror.

Above your pay grade.

Haven’t seen any but a windscreen external sunshade with elastic straps secured by the wing mirrors sounds like what the op needs.

Something like this:

Easily fit without messing with the doors.

Wonder if any exist with magnets inside the material ??

Yes, can get them with magnets.

They are sprung loaded of sorts. If you get a suitable sized one. Then held in place with the sun visors. I use it when parked in sunny spots.

Mine is from Isuzu even though the vehicle is not. I'm sure Isuzu part dept. has them.

Your vehicle dealer probably has one designed to fit your specific vehicle.

As it is inside the vehicle it doesn't get wet / dirty.

Common sense would suggest compromising the door seals would allow water ingress.

In some cases it would appear common sense does not !

If you get the right ones, they're a snap. I used to live in AZ, where the daytime temperatures can easily reach 115 degrees F, or more. Park your car in the sun and it turns into an oven. But the internal shades help a little. They're circular and spring loaded, and you can flip them around to a compact size in a few seconds. Once you take them out of their little case, they flip open and cover the entire windshield.

It might be a good idea to also pry up the plastic or metal carpet retainers on each side, then pull up the carpet and padding to allow it to air out more. The padding will hold water a very long time even in hot climates.

Why do you need to have a sunscreen on when it's raining?

Have you never noticed sometimes here in Thailand its a clear sky blazing hot day 1 minute..... then the sky turns black and it is hammering down the next ?

You need to lift the carpet up and dry it properly or you risk it rusting the steel bodywork.

In my opinion sun screens are useless, it might keep your vehicle cooler but how you going to protect your car paint job.

If you have ownership outside in front of your house get a tent.

Yes and when it does rain or threatens to, I remove the sunscreen because the water, especially heavy rain, very quickly ruins them anyway.

I can see my car from my office, it is an 8 minute walk.

The rain would be done by the time I get there!
