AK Interactive Fine Resin Primer Spray 150ml (#AK1017) is a specialized, high-opacity aerosol primer chemically engineered to adhere flawlessly to poly-resin parts and multi-media miniature components.
Standard hobby primers often struggle to bite into the smooth, non-porous surfaces of cast resin, leading to paint peeling or flaking; this formula is structurally designed to eliminate that issue.
Dries to a neutral, medium grey tone with high hiding power. 
This creates a perfectly balanced color baseline that won't distort the tones of subsequent acrylic, enamel, or lacquer topcoats.
