## Overview

The Hardline Products USA Series 350 Boat Lettering & Registration Decal Kit offers a 146-piece set of solid black, 3-inch marine vinyl decals engineered with UV coating and fuel-resistant properties.

Featuring a super-adhesive formula compatible with multiple surfaces, this kit ensures a sleek, long-lasting finish that withstands harsh marine environments.

## Description

Equip Your Vessel with the Industry Standard in Marine Identification Stop worrying about peeling stickers or failed safety inspections. The Hardline Products Series 350 Registration Kit is the #1 choice for boaters who demand durability and compliance. Whether you are outfitting a high-speed Jet Ski, a family Pontoon, or a fishing Kayak, this kit offers a factory-finished look that stands up to the elements. Why Choose the Series 350? Most generic stickers are made for mailboxes, not marinas. Hardline Products uses 4-mil thick marine-grade vinyl specifically treated with a UV-gloss coating. This means your registration numbers won't fade into a dull gray after a summer in the sun, nor will they curl up when hit with saltwater spray or fuel drips at the pump. Universal Compatibility Our Super-Stick Adhesive is formulated to grip surfaces that standard stickers slide off of. It bonds securely to: • Fiberglass & Gel-coat • Aluminum & Metal • Painted Wood What’s in the Box? You receive a complete 146-decal set (Model BLK350EC), ensuring you have every character needed for your specific registration number. • 4 x Sets of A-Z • 4 x Sets of 0-9 • Total: 146 Decals Installation Tip: For best results, clean your hull with an alcohol-based cleaner to remove wax and oil before applying. Use a strip of masking tape as a bottom guide to ensure your letters are perfectly straight.

Review: Enough Letters - Nice letter kit. The only kit that had enough letters for my boat as it ends with “FF” All other kits only have 1 or 2 “F” and would have had to buy 2 kits
Review: Perfect size and shape for my boat! - I'll start by saying surface preparation is key. I have an older boat that a previous owner had painted with unknown paint. Well the paint is chipping all over the place, so I used letters I knew I would not need to test their adhesion. Washed & dried the test area & the stickers struggled to stick, actually peeled very easy. Decided the failing painted surface was not the best to put the decals on, so I tried everything to get the paint off. That stuff is really tough apparently, ended up hitting it with 220 then 400, then 600 grit sandpaper. Then hit it with a buffer & the original surface shined like new! Guessing the previous owner that painted it was too lazy to shine it up & took the easier way out. So on the freshly sanded, polished & cleaned surface, the sticker hold VERY well. Be sure to tape off the area you are installing them on to get a straight line if it matters to you, or you may waste stickers trying to peel them to straighten out (ask me how I know)... The do not come off very easy at all once stuck to a good surface. Very happy with purchase, may buy more just to have spares in case any get damaged by shoes or dock scuffs.
