SPL urethane chassis foam

[Gurjit]

Anyone heard of this:

*High density rigid closed cell urethane foam can be injected into various hollow parts of a monocque chassis to provide addtional structural strength. For example, a foam filled frame rail becomes much more rigid and resists flexing. Carefully done, urethane foam injection can yield higher chassis strength without the excessive weight from using metal structures.

Caution: urethane foam once set is permanent. In case of an accident, the foam cannot be repaired and it my be necessary to replace the entire panel that was foam injected.*

Heard it also improves the ride and gives better sound insulation. Ideal for ICE!

Note: this is not the same as the expanding foam crap you get in a can from B&Q etc.. That is open cell foam.
