Mr.Hobby GSI-B504 Metal Primer Spray - Strong Base for Metal Components

When you are reworking metal parts on an RC, preparing the surface is key to a clean paint job. The Mr.Hobby GSI-B504 Metal Primer Spray is formulated to promote paint adhesion on metal, helping the finish last through handling and use.

Main Advantages of Metal Primer

Using a primer made for metal reduces the risk of peeling and gives a uniform surface for the topcoat to cling to, which is especially useful on cast or machined parts.

Practical Application Advice

• Wipe panels with a suitable cleaner to remove oils and dust before spraying.
• Shake well and test spray to ensure an even mist before applying to the part.
• Build up colour with light passes and let each layer cure to avoid runs on vertical surfaces.

Who Benefits Most

This primer is useful for hobbyists who frequently update or customise metal components like guards, chassis plates and accessory mounts, delivering a consistent base for final paintwork.
