Will this foam work?

Defoamed SJ. I don't have a Home Depot local to get the pink foam but Lowe's has this. Says it doesn't absorb moisture. Anyone use it or have any input?

It will work they are both extruded Polystyrene.

I didn't see anywhere that said extruded so I wasn't sure if it was or not. I will pick a sheet up and give it a go.

Yes. I used a thinner version on my freak last year.

Thanks @Big Kahuna I might go with the 1" instead of the 2
