Hi all

Up until now I have been using silicone Grease to seal the nib collars on my Montblanc 146 & 149 pens as I don't have access to anything like the Pink Bubblegum silicone that Montblanc use.

Is there anything like their own sealant available to use, I obviously know not to use bathroom silicone or automotive gasket silicone. Is there anything else that I could use.

Thanks

Paul
