02 Galant 2.4 ES

Hello,

I pulled my headliner yesterday due to sagging material. It looks like there are two layers of foam on the substrate.

Can someone confirm the substrate/headliner board is actually very thin material?

It looks like it's about 1/32" thick if I'm right. I would hate to remove a layer of structural foam which is providing shape and form to the substrate.

Photo below is with some of the foam removed showing the substrate board.

Would appreciate some feedback, Thanks
