My DRE diaper is torn a little from flywheel interference. Does anyone know what the black material is or what I could use to patch it with? Will the new DRE owner will sell me a patch? Thanks

I'd call Mike Roth with DRE at 317-403-1814. He worked with me when I had one made last year. Not cheap but fit like a glove. Based on my conversations with him, I expect he will help you out.
