Light Proofing

[piercedpunkonpot]

Im trying to make a two door steel office cabinet into a grow chamber. What do you people use to seal the corners and cracks between the doors and frames of your grow closets? I want to make a lower shelf with a 24hr light for seedlings/clones and then a 12/12 chamber on a shelf above for flowering. What can I use to keep the light from leaking outside of the cabinet when the lights are on and from leaking back into the cabinet when the lights are off. Here is a generic image of basicly what Im working with.

Sandusky 4-Shelf Storage Cabinet available at OfficeMax.com (http://www.officemax.com/max/solutions/product/prodBlock.jsp?BV_UseBVCookie=no&expansionOID=-536896508&prodBlockOID=537039544)

Any suggestions or known solutions?
