exterio rubber trim shrinking

[bonjo]

My car live outside all year round. I have noticed some of the rubber trims around the glass/ windows have shrunk a little. Two questions:

Are there any products other than the likes of meguire ultimate black or 303 AEROSPACE PROTECTANT that are suitable for reducing the problem?

What is a good external sealant/ glue to fill the gaps where the rubber has detached?

thanks

3M weatherstrip adhesive

thanks for the info.
It is not readily available in the UK and aas a result super expensive.
Is it similar to silicon windscreen sealant/ adhesive or to this one below?

Yes, that can probably work too. Please read and follow directions thoroughly. Some of these adhesives can only be applied in narrow temperature ranges.
