Hi Chris, The art of metal finsh goes like this. Use what it takes to remove the scratchs(smooth the ruff metal surface grains). A mirror finish has the least amount of ruff surface grain. A grain of metal sticks above the base metal surface. What your trying to do is smooth the grain down to blend it into the base metal thus creating a mirror finish. The smoother you get the grains the more mirror finsh you will have. The polishing componds:
Grinding wheel--- 30 grit to 300 grit flapper wheels---emery paper on a rotating disc, 30grit to 800grit Rouge--- a stick paste of very fine polish, 800grit to 1000 grit Electroplating--- the mirror finish by filling in the grain "valley" with very fine metal particles left over from the above metal pre-prep. So as you can see from the above, you start with a ruff grinding wheel and keep going with finer polishing compouds until you reach the desired finish. Thats the basics of metal finishing. Now you have to read about how and what is used to accomplish this task and that you will need to read books on metal finishing as it way to much typing for this forum to explain it all. Watch and clock maker suppliers have a cheaper cost on the very fine polishing compounds. Auto-body suppliers usaually have the cheapest cost on the ruff finishing compounds. All are available on the internet. T_Bone
