Wasn't sure where to post this so putting it here. I have a project where I need to insulate some buckets. I want some kind of insulation solution that won't absorb water. So taking a 5 gal Home Depot bucket, any thoughts on ways to get say 2" of spray foam insulation all around it? Could be more, hate to go less than 2". Random thoughts welcomed. Thanks

Edited to include, I need 5-10 of them.
