I have been buying from him for years. New toppers need some breaking in. Quartz works fine breaking in but the first few stones will have some scratches. Batt with 3000 will take care of them. For a beginner diasticks would probably be the way to go, easiest to learn how much and technique. I use oil, usually WD40, squirt on paper towel and apply then wipe almost all off then apply loose diamond sparingly and rub in with finger. If use you too much diamond or oil you can try wiping it of with a piece of paper towel and try again. It has been years since I used any of my diasticks but they work pretty much the same. Put some on, spread it around lap then wipe some off. With practice you will learn how much to use and omit wiping off.
