Every marking on a model — the unit numbers, the warning stencils, the squadron badges — gets there one of three ways: a waterslide decal, a dry transfer, or a sticker. Kits usually ship with stickers and sometimes waterslides in the box; aftermarket sheets sell the good stuff. They look wildly different on the finished model and demand wildly different amounts of patience, so the choice is really a trade between how good it looks and how likely you are to ruin it. Having catalogued the markings and setting products builders use, here is the honest ranking.
The quick answer
Waterslide decals look the best by a wide margin — thin, paint-like, and near-invisible when set and sealed properly — but they take the most work and a setting solution to get there. Dry transfers are also film-free and beautifully thin, yet they are one-shot and unforgiving, and increasingly hard to find. Stickers are the easiest and most durable to apply, and the thickest and shiniest to look at, prone to peeling at the edges over time. Best result: waterslide. Least risk: sticker. Dry transfer is the specialist in between.
Head to head
| Waterslide | Dry transfer | Sticker | |
|---|---|---|---|
| Look | Best; thin, painted-on | Excellent; film-free | Thick, glossy |
| Difficulty | High | High (one-shot) | Low |
| Carrier film | Yes (must hide) | None | It is the film |
| Conforms to curves | Excellent with solution | Poor on curves | Fair |
| Permanence | Permanent once sealed | Permanent | Peels over years |
| Availability | Wide (aftermarket) | Shrinking | In most kits |
Waterslide: the display-quality standard
A waterslide is a printed marking on a clear carrier film, mounted on a paper backing. You cut it out, soak it in water for a few seconds until the film releases, slide it off the backing onto the model, position it while it is still floating, then wick away the water and let it dry. Done right it looks painted on. The catch is silvering — light trapped under the carrier film around the printed area, showing as a dull silvery halo — which is where a setting solution earns its place. A softer/setter set like Mr. Mark Softer and Setter softens the decal so it melts down over surface detail and drives the film tight to the plastic, killing the silvering. The full soak-slide-set-seal routine is walked through in how to apply waterslide decals.
Dry transfer: thin but one-shot
Dry transfers (rub-on transfers) carry no film at all: the ink sits on a backing sheet and transfers directly to the model when you burnish the back with a stylus or pencil. Because there is no carrier film, there is nothing to silver and nothing to seal against — the marking looks as thin as paint. The price of that is brutal: they are a one-shot deal. Once you start burnishing, the transfer commits where it lands, and you cannot float it into position like a waterslide. They also resist compound curves and have grown scarce as waterslides took over the hobby. For a flat surface and a steady hand, they are gorgeous; for a beginner on a curved mecha shoulder, they are a heartbreak waiting to happen.
Stickers: the no-risk default
Stickers are exactly what they sound like — peel and press. They ship in most kits, especially snap-fit Gunpla, and they are genuinely the right call for a first build or a kid's build because nothing can go catastrophically wrong. The downsides are cosmetic and long-term: the marking sits on a visibly thicker, often glossy film that catches light differently from the paint around it, they do not hug compound curves as cleanly, and the edges can lift and peel after a few years. Foil stickers for small metallic details are the one case where a sticker beats the alternatives outright.
Killing the shine and the silver
The step that unifies all three is the topcoat. Even a perfect waterslide sits on a faint film edge, and every marking reads differently against a glossy versus a matte surface. The pro sequence is to apply decals over a glossy coat — gloss gives the film a smooth bed and prevents silvering — then, once everything is dry, spray a clear flat over the whole model so the decal sheen matches the paint and the edges disappear. A matte topcoat like Mr. Super Clear Flat is the standard for that final unifying coat. Because it is a lacquer aerosol, treat it with the ventilation it deserves: spray in a booth or at a fan-vented window and wear an organic-vapor respirator, exactly as you would for any lacquer clear. The matte-versus-gloss and frost-risk details are in how to top coat a model and Mr. Super Clear vs Testors Dullcote.
Which to use when
Match the marking to the build. Contest piece or a display model you care about: waterslide, set and sealed, every time. A child's first snap-fit or a quick shelf build: the box stickers are perfectly fine and far less frustrating. A flat-surfaced subject and a marking you can find as a dry transfer: enjoy the film-free finish, but practice on scrap first. And whatever you apply, remember markings are one layer of a detailed finish — an enamel panel-line accent worked into the recesses first, then decals, then a flat coat, is the order that reads "built," not "assembled." Where these detailing steps sit in the wider workflow is mapped on the bench.
The verdict
If you want the best-looking model, use waterslide decals and learn the setting-solution-and-seal routine — it is the single biggest jump in how "finished" a build looks, and it is not as hard as it first seems. Dry transfers are a lovely, film-free option for flat surfaces and steady hands, hampered mainly by their one-shot nature and shrinking availability. Stickers are the honest, low-risk default that ship in the box and belong on first builds and casual ones. The real upgrade for most builders is simply graduating from box stickers to waterslides on the next kit that matters.

Questions builders ask
Are waterslide decals better than stickers?
For looks, clearly yes. A properly applied and sealed waterslide sits thin and paint-like, hugging surface detail so it reads as printed-on, while a sticker sits on a visibly thicker, glossier film that catches light differently and can peel at the edges over years. The trade-off is effort: waterslides need soaking, careful positioning, a setting solution to prevent silvering, and a topcoat. Stickers just peel and press, which is why they still belong on first and casual builds.
What is silvering on a decal and how do you prevent it?
Silvering is a dull, silvery halo around a decal caused by light reflecting off tiny air gaps trapped under the clear carrier film. You prevent it two ways: apply the decal over a glossy surface, which gives the film a smooth bed with no micro-texture to trap air, and use a decal setting solution that softens the film so it melts down tight against the plastic and surface detail. Sealing with a clear coat afterward hides any remaining film edge.
What is the difference between a waterslide decal and a dry transfer?
A waterslide has the printed marking on a clear carrier film that you soak, slide off its backing, and position wet on the model — flexible to place, but you must hide or seal the film to avoid silvering. A dry transfer has no film at all: the ink sits on a backing and rubs directly onto the surface when you burnish the back. Dry transfers look thinner with nothing to silver, but they are one-shot and cannot be repositioned once you start.
Do you need to seal decals with a topcoat?
You do not strictly have to, but you should on any model you care about. A clear topcoat protects the marking from handling and wear, and — more importantly for looks — it unifies the sheen so the decal's film edge blends into the surrounding paint instead of sitting on top of it. The usual approach is to apply decals over gloss, then spray a clear flat over the whole model. Because most flat clears are lacquer aerosols, use proper ventilation and a respirator when you seal.
