We where working on some prop armor and I found the Hydrospan because the helmets where a little off and I thought we could size them up with it. Sorry to say it didn't work asadvertised. We tried it oneverything, And I mean everything, large and small, that we could think of with the same thing happening. Unevenexpansion.We call thecompanyto see if they could help but nothing worked. So unless they have changed it don't be shocked if it don't work.<div></div><div>Baron</div><div></div><div>Helmet</div><div></div><div></div><div></div><div>Armor</div><div></div><div></div>
