Review on 20 Sheet A4 Size Inkjet Waterslide Paper For DIY Decals, Ceramics, Candles, Custom Tumblers, And Gifts - Clear Waterslide Decal Paper For Crafts (Packaging May Vary From Blue) by Dave Wolf

I used these waterslide decals on painted aluminum that had been sealed with Krylon Clear Coat. They work great. Just be mindful of the following:(1) be sure to print on the correct side.(2) let the ink dry *fully*, and then clear coat the decal paper *thoroughly* BEFORE applying it. Don't glop the clear coat on, but use several light coats to get a nice even coat of clear that seals the ink in.(3) Be patient with bubbles when applying the decal. It may be difficult to squeegee out the bubbles without moving the decal around, especially if you're applying a larger decal. Let it dry a bit under close supervision (a couple of minutes maybe), and then work the bubbles out as the decal starts to "grab" the item you're applying it to. It may take a few rounds of letting it dry a smidge and then working out the bubbles to get a good final product. It'll never be perfect, but with some patience you can get great results.(4) Don't expect to be able to apply this to a dark surface. Inkjet ink doesn't go on that thick, and these decals are clear-- a dark background will show right through, and the brightness of your design will be completely gone. Apply it to a lighter background and it will work great.
