[QUOTE="Dughug, post: 57760, member: 157"] G'day Wally, the cerium oxide & tin oxide are really good on the Perspex lap for quartz & generally any thing with a hardness of 7 or less. Linde A is also a form of Cerium Oxide. I've used Lapsa but generally now I stick with Cerium 7 Tin Oxide. I put about a tea spoon in a spray bottle with water, Metho & a couple of drops of lavender oil. I then spray it on the lap. the lavender oil provides a slight viscosity on the lap but generally I use it to make the Adelaide water smell better! With your copper & Tin Laps you'll need to obtain some diamond grit & / or spray to use on your stones harder than 7 - I use 3k for pre-polish 14k, 50k then finish on 100k. The best way is to try what works best for you. Cheers Dughug :) [/QUOTE]
