Burned out my stock seals doing a cleaning burn and getting distracted... So, I've got a couple of questions;
Most of the seal came off with some very gentle persuasion from a paint scraper, but some cottony bits remain - how do I get those off?
How clean does the surface need to be? In some spots, it cleans easily all the way down to unglazed ceramic, in others there's a stubborn black glaze.
