"Final" Render is acting weird

Hi, so I dont know why, but when in the 3d viewport my render looks all fine (using cycles), but as soon as I hit F12 to render it, it does some weird things :S See image.
What am I soing wrong? Also posting my .blend if you want to look around.

Thanks

You got the gray base mesh on a layer that isn’t activated in the viewport but is an active layer for rendering?
You got the gray base mesh hidden with H on a layer? It will not show i the viewport but in the render.

fail… yeah that was it, it was more of a first bottle model test, forgot I even had that mesh there…

but thanks! :slight_smile:
