Some resin manufacturers endorse polishing with a Dremel. I have found, that if using a quality pit filler. I can achieve equal results polishing by hand than that of Dremel polishing. The exception to this may be in very large pits that are deep. One word of caution. Watch the heat build up when using a dremel. High speed polishing results in high heat.. Just use care.
And, not to be confused with the "new" glassdoctor. I am the original "Glassdoc".
