How can I remove this adhesive?

[PranK]

A lot of the trim pieces on the E39 are super brittle and just dissolve when you try to get them off. It looks like a previous owner has used what can only be described as an industrial construction foam adhesive to glue down a tiny piece of trim. 

Unfortunately this part of the tailgate is starting to rust because of how much shit is in here. This is stopping the water draining and there's a big build-up of dirt that is just staying wet.

How can I remove this? Would a flap disc get rid of this? 

I think this car spent a lot of time inland. There's so much light coloured, fine dirt and dust everywhere. 

Sorry for the pic. I've cleaned this all up now so I'll get another pic of it clean today.

Here it is nice and clean and for shits n giggles he's the clearly structural piece of trim it was holding down. 😬

My first thought is to use something like this

Warm it up with a hair dryer or gently with a hot air gun.

I would soak the foam with this stuff for about 10 mins then scrape off

Beauty, thanks guys, got some ideas now. I note that none of you agreed with the flap disc so that's good to know. 👌🏻

If by "flap disc" you meant "chocolate wheel".... then they are OK for getting off stubborn remnants. But not for stuff with bulk depth.

If by "flap disc" you meant "abrasive paint f**ker"....

You've got yourself a good old game of have fun.

That shit is annoying as hell to remove. Thankfully for you, yours is on metal, most of the stuff I take it off is plastic, so typically hear guns are out.

I normally end up continually dragging my thumb with pressure over it to get it to peel up. Eucalyptus oil then works well for getting residue and last remnants off.

 

Edit: plastic scraper might be worth while too. One that'll dig into the foam tape, but not scratch the paint.
