Nuvite Chemical NuShine II F9 – Aviation Metal Polish (Brightwork)

Grade F9 – this grade is a compounding grade with a very coarse grade particle size, useful on severely corroded aluminium and new aluminium. Nushine F9 is used where the surface has been damaged by corrosion, has severe pitting, or has had severe stripping processes, including being sanded or scratched by abrasive cloth. Never use standard commercial grade sanding
papers –even wet, on aluminium to be polished. Alternatively, there are speciality micro fine surface sanding materials (speciality grade abrasives –not commercial grade sandpapers) that may be helpful in really severe situations before using Nushine F9.

But F9 is a good surface blender and is useful even for non-clad aluminium, forged and cast aluminium, stainless steel and titanium and anodised surfaces needing special procedures because of the surface hardness. Usually, it is necessary to follow Grade F9 on aluminium with Grade G6 or C for further surface preparation prior to final finishing with Grade S.

Nushine II Grade F9 is a heavy-cutting compounding grade polish that we recommend using for prep of already polished surfaces prior to using Grade S.
