what is the correct way to use a dremel to trim out dead spots on a monti cap so that it may grow back and not cause further damage in the process.or should i use something other than a dremel?i cant get to the back or underside very well with the cutting wheel or any of the other bits provided due to lack of space.will cutting out from the top prevent re-growth?this is new to me and i want to do it correctly--thanks
