[Zope] Setting Default Roles/Permissions for product

How do I set the default roles of for a Python product's permissions (keep in mind I have added 3 new roles) programmatically inside the product code? In my product classes, I use ClassSecurityInfo and I do make sure to InitializeClass after declaring all my security settings. In my security declarations, I include multiple lines similar to : security.setPermissionDefault('Add records', ('Custodian')) My permissions are shown on the main security tab. However, some of the permissions pick up the default roles, some do not, and others have NO roles defines. Can someone please point me in the right direction? Thanks in advance!!
