When I polish Ali ,stainless with an electric buff and compound I get a grey wax residue on the work piece. Can I minimise this , am I pressing to hard , to much compound ? Also what’s the easiest way to remove it ? Thanks
Too much compound the final finishing should leave virtually no compound any residual can be cleaned off with thinners or in the case of Ali,brass I just clean it off when coating with a chemical coating like extra gloss protection. Polished Ali will dull with thinners and some cleaners.
The reason why you are having those problems is heat. You are simply not generating enough heat to melt the compound, therefore it smears. Are you using some light weight home type of kit? This is the most common problem with lightweight gear. The main of the heat should be generated in the rough polishing stage then carried forward to the final polishing stage. 2 stages is ample to a very nice finish that most will envy other than if you are doing jewellery.
You cant really put to much soap on because it will just polish off if you have the correct heat generation. You should not be able to hold the part with your bare hands. I nearly always have to wear 2 sets of gloves (pending the parts and the application) and then you still get your hands wrecked. You will probbaly get an imperfection where the soap smears unless you can get the heat input, to clean the parts you can use a paraffin bath, diesel and white spirit will do the same job as they are the same oil base, this will actually physically dissolve the soap, after that use hot water and washing up liquid and you will have beautiful parts.
The first ones are ally, The rectangle bezels are stainless and i had to do about 250 of those and polished on the insides too!
