Tamiya 69951 Surface Primer Spray for Metallic Paints  [69951]

Surface primer for metallic paint finishing

Tamiya 69951 is a surface primer spray formulated to prepare hobby scale models and Tamiya kits for metallic topcoats. It creates a uniform base layer that improves adhesion and reduces mottling when using metallic paints, helping to achieve even coverage before final finishing.

Use context: apply on clean, dust‑free plastic or resin model panels. Lightly sand glossy areas with fine abrasive (800–1200 grit) and remove residues before spraying. Hold the can 20–30 cm from the surface and apply several thin, even passes rather than a single heavy coat to avoid runs and excessive texture.

Practical tips: test on a scrap panel first to confirm spray pattern and drying speed. Allow short flash‑off between passes (about 5–10 minutes depending on temperature) and full drying per label instructions before applying metallic paint. For best results, keep ambient temperature stable and avoid high humidity while spraying.

Maintenance note: the primer aids adhesion and surface uniformity but is not a polishing compound—allow complete cure before wet‑sanding or buffing the topcoat. Store the can upright in a cool, ventilated place and follow standard hobby safety precautions when spraying.
