Outer Limits 4x4 Board

Anyone know what they use to stick the plastic sealing sheet on the door?

I have to replace my window rubbers and the sealing sheet is pretty farked, so I thought I get a bit of poly and make a new one. Just wondering what that white stuff is they stick 'em on with

Thanks

Martin
