Brumby Fastcut Cutting Compound is best used to “cut back” light scratch marks on copper, brass and stainless steel, steel and aluminium prior to polishing when in use with a josco stitched sisal buff
Different metals have varying characteristics, and to achieve the best possible results it is essential that the correct polishing compound and buff are selected for the job.
Directions for use:
Most buffs have a tapered centre bore, and may be mounted on the left or right of your grinder using a tapered spindle.
Select the correct buffs and compounds for your job. Initial cutting can be done with a fastcut compound and either a stitched sisal or a stitched rag buff followed by a polishing compound and a loose leaf buff. For best results, never use different compounds on the one buff – keep a separate buff for each compound.
Apply the compound across the face of the rotating buff for a few seconds, taking care not to apply too much compound which will overload the buff. It is far better to apply a little compound more frequently than to over dress the buff.
After applying the compound to the buff, bring the work piece into contact with the buff and with light pressure, move back and forth across the job.
After polishing, remove any compound residue left on the work piece with mineral turpentine or methylated spirits, or warm soapy water.
