The point I was inferring was that the the 4-6mm HDPE armour wasn't NST proof & I would never recommend anyone else try to copy it.

I consider Explosion's strengths not to be the armour (I've never counted structure as armour BTW) but the strong build, the excellent design & superb driving.

These strengths are why it survived NST, not the plastic or hardox frame. You quite literally couldn't duplicate Explosion.
