Home Forums Hunting & Shooting Rimfires Suppressor for 22LR on my 'To Get' list

I have the YHM Mite, love it, but really need to send it in for the upgrade.

While we are talking 22 suppressors, is there a trick to preventing lead build-up on the inside? I was told to coat the insides with Frog Lube, but that does not seem to help.
