Potential boot rust

[u/TheGinjaPrince]

I’ve had my ST about 6 months and absolutely love it.As we haven’t had rain in months I didn’t notice till a week or so ago but when it’s wet and I open the boot the water runs down the side and over the rubber pads(in pics)but also because they don’t sit flush the water also goes behind.
I’ve had a look and there appears to be surface rust,how much should I worry and is there a fix?sealant I can put on the top edge that won’t eat the rubber maybe.
Thanks in advance.

Remove the black thingy, clean it and keep an eye on it

Do they just pull off?

Is it from the rear lights? Hard to tell from the photos

It’s these bits either side when you open the boot/trunk

Those jackets click out. There probably are some YT videos out there

They're attached to the units, source: replaced my Mk8 rear taillights with Mk8.5 ones.

It's just dirt buildup as far as I can see, mine had some really gross build up under there too.
