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.

    • Enough Letters
Color: Blue
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

    • Perfect size and shape for my boat!
Color: Black
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. ... show more

Unfortunately, these don't work on a seadoo spark trixx. Would be great on all other boat surfaces.

    • Simple and very reliable boat letters. Amazing for the price.
Color: White
I bought the black version for my old boat two years ago. I was truly impressed with how well they held up. They didn’t peel, crack, rip, nothing. They’re a thicker cut with a good adhesive. Two years later they were just as good as when I put them on. Got my new boats lettering installed today which was this white pack. I have no doubt this will last for a very long time. Highly recommend. ... show more
