Oh no, that's frustrating! It sounds like the sealant and the stickers aren't playing nicely together. Think of it like trying to glue two different types of paper – sometimes the glue just doesn't stick right. Instead of more sprays, let's try something that acts like a super-thin, clear sticker over your stickers. Look for a self-adhesive laminate sheet, like the kind used for protecting photos or documents. You can find these at most craft stores or online. Just carefully cut a piece slightly larger than your stickers, peel off the backing, and smooth it over the stickers. It'll give you that smooth, clean finish you're after without the risk of streaks or peeling.

Ah, a classic case of material incompatibility! Let's break this down. Krylon clear coat is typically an acrylic lacquer. Many stickers use a vinyl or polypropylene base with an acrylic adhesive. The problem arises when the solvents in the Krylon interact unfavorably with either the sticker's ink, the adhesive, or the plastic of the case itself. This can cause the adhesive to soften, the ink to lift, or the plastic to become brittle, leading to the flaking and peeling you're experiencing. Multiple coats in a short period only exacerbate the issue by increasing solvent exposure. Before switching to Mod Podge (which, being a PVA-based adhesive, *might* be gentler, but still carries risks), consider a few things. First, what material is your laptop case made of? Is it a hard polycarbonate, ABS plastic, or something else? Second, what kind of stickers are you using? Knowing the chemical composition of both the case and the stickers will help you choose a sealant that is chemically compatible. Ideally, you'd test a small, inconspicuous area with a different sealant before applying it to the entire surface. Look for sealants specifically designed for plastics and adhesives, and always apply in thin, even coats, allowing ample drying time between each. A flexible sealant might be a better choice, as it can accommodate any slight movement or expansion/contraction of the materials.

Hey there! Bummer about the sealant situation – I know how frustrating it is when a project doesn't go as planned. It sounds like the Krylon clear coat might not be playing nice with the material of your laptop case or the stickers themselves. Compatibility is key! Before you try Mod Podge (which can work, but you're right, streaks are a risk), I'd recommend a few things. First, gently remove the flaking sealant with a plastic scraper to avoid scratching the case. Then, try a **thin** coat of a **flexible** sealant specifically designed for plastics. Look for something like a clear acrylic lacquer or even a product marketed for sealing vinyl decals. Always test a small, inconspicuous area first to make sure it adheres well and doesn't react negatively with the stickers. Good luck, and don't give up! Every project is a learning experience.
