buffing trim tips needed

Well I can get you started. Pot metal can only be plated- no polishing. The plater will do whatever repair is needed to make the surface smooth and ready for plating. Stainless is a very hard metal. It is usually worked and straightened like bodywork with little to no sanding because it will require so much polishing due to its hardness. In extreme cases it can be welded and ground down for repairs. Aluminum is very soft and usually anodized. The anodizing should be chemically stripped or polished through. It can be straightened with a minimum of sanding. It can be left natural or be re-anodized. If left natural it will need occasional polishing or waxing because it will oxidize without anodizing. In extreme cases it can be welded, but you run the risk of it not matching the rest of the un-welded trim. Door sills- this is my personal choice- I take good originals and lightly polish them. This preserves the original details but is more expensive. I am not a big fan of reproduction stuff.
