I don't think he did. I think he did something similar to Kerry in letting reporters view his full personal collection of records for a brief period of time (This time last year)
I know he "ordered" all his records to be released, but I don't think it ever involved signing form 180.
The AP and other news organizations who filed an FOIA request to get Bush's TANG records were able to get them because of the signed 180 and Kerry's were denied to them because he hadn't signed it.
