Most Common Buffing Polishing Error:
This cannot be stressed enough.
When trying to achieve a fine or polished surface finish you work in stages.
Do not move on to the next stage until you are completely finished with the current stage.
If you skip steps or do not completely finish each then you either pay for it with extra labor or end up with a poor job.
Machinery can speed up the process but replaces steps in the processes at the cost of efficiency and wear and tear on the equipment.
