How to shoot through curved glass

[Ginu]

Well I figured its either something I cant figure out, or I'm doing something wrong.

The curved glass does project the image a little distorted or perhaps magnified but by any mean it does not look out of focus, however with the DSLR it doesn't matter if I let the camera to do the metering or i do it fully manual because its always out of focus...

Oh and ofcourse I try taking the photos with the pumps off... only works on the sides tho ah well

If anyone else has suggestions, please pot them up, I'm sure it will help a few people.
