Unveil me the ark please! how do you view an object without transparency? I want it solid! Do you see it so why it is not closed somewhere? or maybe why is it an alias file (.wire)? I cuffed with textures, materials etc, there is no verse, always stays like that!
no, if you want you can remove the "translucency" check and see it as solid
If you want, try using the "sculp" command and make it solid.
if it is correctly closed, it should work
