Hardline USA Series 350 Boat Lettering & Registration Decal Kit

The Solid Black 3-Inch kit covers letters and numbers with 146 pieces, designed for hull lettering and registration. It is UV coated to resist sun exposure and meets USCG guidelines. The kit’s fuel-resistant vinyl helps prevent fading from gasoline exposure. Best for boat owners seeking a straightforward, all-black appearance with durable performance.
