Aluminum
General Information:
Untreated Aluminum is divided in soft and hard aluminum.
The surface of pure aluminum is normally protected by a thin layer of oil; use selected cleaning products to remove the oil coat.
Coated aluminum parts which are to be recoated, must have any old unsound coating completely removed by sanding, scuffing or suitable beam technology for the new ***sustainable coating***.
An anodized coated surface is very hard and almost impossible to create a suitable key for painting, therefore avoid applying paint product to anodized coated aluminum for a new sustainable coating.
