Sprinter side trims

Morning all, sorry to post again. I was just wondering if folks think I should fill these two oval holes that are behind all of the side plastic trims on this sprinter van. The holes go right through to the inside of the van. Fibre glass over them do we think?

Greetings!

All of the euro vans are notorious for leaking water behind the trim, even the small holes.

Cheers!

Yeah it’s a very daft design I must say! Shame no one has made blanking grommets for those oval holes! Be much easier than me having to fibre glass them!

Greetings!

One guy I know cut a piece out of a smooth plastic water bottle, the attached it with double faced 3M tape.

Cheers!
