Hetty took in some water over the weekend. It pours in through the vent flap!

Obviously this is issue number one to solve.

The water seems to have gathered here



Which given that this is primary rust territory is a bit of a concern.

I need to stop the water getting in, but would it also be a good idea to heat up some waxoyl and really pour it into that gap?

Also, the round hole in the centre of the chassis top plate - where does that lead to? I'm concerned water may have got in there.

Narnia my friend, it's a wonderful place!

Wonderland?

That's more like it, say hi to the mad hatter for me!

i thought that was Alice in Wonderland!!

Mine does that, it's probably the worn wiper spindles letting water in rather than the flap, unless your flap is obviously holey and the rubbers fecked.
I drilled some holes in the floor pans at the lowest points to let the water out ,painted and waxoiled or ankor waxed the newly drilled holes on the exposed metal ,and then put some thin kitchen drainer plastic things under the floor rubber to assist with airflow for any dampness to dry quicker and so there's not water sandwiched against the floor for ages when i forget to lift the mat.
I suppose i could just source the leaks and fix them, but seeing as it's a 2cv i gave up hope and did that instead
Perhaps that hole in your chassis is the last owners attempt at a drain hole ,i think it would run into the chassis box and out of a drain hole somewhere
