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. These can be easily polished or used as-is.
- Seconds are fully functional reservoirs that:
- May have minor inconsistencies in appearance of welds. (Perfect for those who want to grind/sand off the welds).
- Have heavier scratches or tooling marks than Natural reservoirs.
- Have other minor visual imperfections
