Hi All, I have been having an increased amount of folks sending me shutters in baggies... I have no problem with people wanting to save money and try to clean shutters themselves, like the old compur, ilex, alphax shutter but I would I would advise that it's best to let someone with repair knowledge to take care of your Synchro-compur shutters. They are a complex shutter with many springs and levers and in most cases when folks try, they end up sending them to me or an other repair facility in baggies many times with missing or broken parts. So save your baggies and if you have one of these shutters and it needs to be cleaned, leave it to knowledgeable person. Thanks!
