I seem to recall Bill Sherwood saying that soaking them in hot water makes it easier to peel off the glue or scrap it away ... but then again, don't quote me on this.
Just do a search either on these forums, www.twincam16.com or failing that, try his own web page - www.billzilla.org
The clips by the side are only an added protection - you'll still have to get rid of the glue.
