To properly prep metal for epoxy primer, start by cleaning the surface with a solvent-based cleaner to remove any oil, grease, or dirt. Follow up by sanding the metal with a medium-grit sandpaper, such as 180-220 grit, to create a surface that allows better adhesion of the primer. Ensure that all rust and corrosion are removed during this process, using a rust remover or converter as necessary. After sanding, thoroughly wipe down the metal with a tack cloth to remove all dust and debris. If you're working with bare metal, applying a metal etch product before the primer can enhance adhesion and corrosion resistance. Finally, apply the epoxy primer in a well-ventilated area, following the manufacturer’s instructions for the best results.

Yes, reinked ink cartridges often require a vent hole for proper operation. This hole is crucial for maintaining air pressure balance inside the cartridge, which ensures consistent ink flow to the print head. Without this vent, ink could fail to be released efficiently, leading to poor print quality or even damage to the printer. Most ink cartridges are designed with a pre-existing vent, but when refilling, it's essential to ensure this vent is not clogged. If resealing is needed during the refilling process, one must take care not to obstruct the vent area. Proper venting is especially vital for cartridges in printers that rely on gravity and capillary action for ink delivery.
