Finish Notes
Finish Notes
- Natural reservoirs are aluminum in an unfinished state. They may have minor scratches and tooling marks. Weld etch lines will be visible.
- Polished reservoirs will be polished on all outward facing panels. This is a mirror polish. Fill caps are also polished. Firewall side (back) is unpolished.
Due to regular changes in material availability since the tariffs were implemented, slight color variations in 5052 aluminum have been noted. Our current Coolant Reservoirs are slightly more gray in color than our current Washer Fluid Reservoirs.
