Flex Seal


Sr Member
Anyone heard of this stuff?

I feel like that could be useful for sealing seems in foam costumes.

I'm fairly certain it's the same stuff as Plasti-Dip, which is used to seal most foam costumes that people here make.

flex seal is pretty much exactly the same as the rubber undercoating sprays you can get at an automotive store. I'd suggest trying that if you want to do some tests, as it's much cheaper than flex seal.
