Bon permanent seal for collar?

[Ramdough]

What is everyone using to seal a wood and 2" foam collar?

I am looking for a non- permanent installation so I can swap freezers if mine craps out one day.

Keezer is going outside, so I need a good seal.

Thanks

Silicone usually can come off pretty easy
