HOW TO USE THE BUFFING COMPOUND?
- Choose the right buffing compound.
- Attached the polishing buffing wheel to the bench grinder, drill, angle grinder or polisher.
- Run the bench grinder, drill, angle grinder or polisher you used, apply the chosen buffing compound to the polishing buffing wheel for approx 2 seconds. The buffing compound is wax/abrasive based, so the motion of the spinning polishing buffing wheel generates heat which melts the wax/abrasive onto the polishing buffing wheel.
- Apply the polishing buffing wheel to the item to be polished.
- Apply more buffing compound during polishing if required.
- Change the polishing buffing wheel for the next polishing stage if needed, and repeat the process with a finer buffing compound. If you use the same polishing buffing wheel for different polishing stages, rake the polishing buffing wheel thoroughly and remove the previous buffing compound before changing from one compound to another.
USEFUL POLISHING TIPS
- Use compounds sparingly, black grease marks will appear on the workpiece if too much compound has been applied to the buffs. Remember little and often.
- If it is possible, polish across marks and scratches not along them.
- Use a different buff for each compound.
- Do not mix different compounds on the same buff, Clean the buff off with a wire brush or buff rake before applying a different compound.
- Attach the tapered mandrel to your drill, or angle grinder adapter to your angle grinder/polisher or bench grinder spindle adapter to your bench grinder and fix tightly.
- Try to constantly vary the directions of which you polish. This is not always possible but recommended as some articles may be of an unsuitable size and shape.
- If you are polishing small articles then you can fix your drill into a vice, this will enable you to polish these small articles with ease.
- Sometimes when you have polished you may see a slight coat of black grease or finger marks on the workpiece, these can be removed with the microfibre cloth.
- Protect polished articles with a good wax polish.
- If you wish to electroplate or lacquer to the polished article, make sure you use an as good degreaser and do not protect with a wax polish. Any dirt or grease or wax will interfere with the adhesion of the plated metal or lacquer.
