I'd get a sak to be honest mate. It's all metal, easy to strip, cheap and effective. I wouldn't be happy using a mod with some fibrous wadding inside for the reaons outlined above and because what has happened can happen. Not much help i know but just my honest thoughts mate. I can't think how you'd make the mod good again, other than soaking the wadding in something to get the crud out, drying it out and then putting it back in. Have you tried contacting Hogan? They may have some they can send you.
