New-ish to pipe smoking. Bought a Savinelli Roma #305. by accident i spilled a bottle of rubbing alcohol onto it and it got all over the beautiful briar grain on top of the bowl. Some of the stain came off but its still kind of OK just way duller than before, and when i light the bowl i can see its more susceptible to rim darkening.scorching. Is there a wax or something that I can apply to 'protect' the rim better. I know that no wax or seal or chemical wont prevent rim scorching, only better technique, but any advice would help. Thanks in Advance.
