Mr.Hobby B611 Aqueous Surfacer 1000 Spray Primer  [GSI-B611]

Prep your model surfaces with Mr.Hobby B611

The Mr.Hobby B611 Aqueous Surfacer 1000 is a water-based primer spray developed for hobbyists who want an even undercoat. Its fine particle mix helps paint stick better and fills light surface imperfections for a smoother topcoat.

Why a water-based surfacer works well

Compared with solvent primers, water-based options like Mr.Hobby B611 are lower in fumes and easier to handle in smaller workspaces. They dry quickly and allow simple washout with water, reducing solvent use during cleanup.

Application technique for consistent results

Ensure parts are free of dust and oil before spraying. Shake the can vigorously, then apply thin, even passes from about 15-20 cm away. Let each layer dry fully before applying the next to avoid sagging.

Works across multiple RC platforms

The Mr.Hobby B611 Aqueous Surfacer 1000 is suitable for RC cars, foam planes with painted reinforcement parts, and model boats. It bonds to plastic, metal and resin, offering flexibility for mixed-material builds.
