Review: Excellent Upgrade for Cleaner, Smoother Prints – Worth Every Drop - I was skeptical at first—3 mL didn’t sound like much for the price—but after using Slice Engineering’s Plastic Repellent Paint, I’m convinced this little bottle punches far above its weight. If you’re tired of cleaning off burnt filament crust from your hotend or suffering from inconsistent extrusion due to buildup, this product is a game-changer. Pros: Actually Works: Once applied to the nozzle, filament just slides off like it’s scared to stick. Even when printing with notoriously sticky materials like PETG, there's significantly less gunk buildup. Easy Application: It comes with a precision brush built into the cap, so applying it to the nozzle is simple and mess-free—just don’t overdo it. A little goes a long way. Improves Print Quality: Cleaner nozzles mean more consistent extrusion. After applying this, I saw cleaner layer lines and fewer blobs on prints. Long-Lasting: Even though it’s only 3 mL, I’ve done multiple nozzles and still have plenty left. You’re not meant to slather it on—just a light coat does the trick. Safe and Water-Based: Unlike some mystery coatings out there, this one’s water-based and PTFE-based, which gives some peace of mind when using it near heating elements. Cons: Price per mL: It's not cheap, especially for such a tiny container. But considering how long it lasts and how much trouble it saves, I’d say it balances out. Needs Reapplication: Depending on your printing frequency and materials, you might need to reapply every few days or weeks to maintain the effect. Don’t Get It on the Heater Block Threads: It’s easy to be a bit sloppy at first. I recommend removing the nozzle for a clean coat or being really precise. Final Thoughts: If you 3D print often—especially with high-temp or sticky filaments—this paint is a fantastic quality-of-life upgrade. It helps reduce maintenance, improves print reliability, and keeps your hotend looking brand new. I’d recommend it to hobbyists and pros alike.
Review: It saved me a few nozzles. Works great if you follow instructions. - This has genuinely paid for itself in saving 2 (silicon carbide) nozzles from the blob of death. I thought I was cooked when I saw it bulging out from under the hot end cover but it didn't stick to the nozzle. It just fell off when the printer returned to the home position after cancelling. It's some a magic, bug spray for plastic. Things can still melt around the hot end but this will stop them sticking. Most situations it falls off during movement. You're going to need to reapply depending on how often you print and circumstances. After my save from the blob of death, I definitely reapplied. I have 3 printers that I typically run 4-10hrs a day and find I need to reapply every few days. I have no idea if it's a time or temperature/use situation. It seems to work like an advanced layer/mold release. Given it works on really hot metal I'm guessing a boron Nitride solution which after evaporating, leaves a release coating on the metal. It's a small bottle with a nail polish like applicator brush and dead simple to apply. It takes very little to cover the exposed parts of a nozzle. You need to apply prior to heating up the hot end or it evaporated but with so little needed it's dry by the time I'm done and back to my computer, start the print and the hot end is at business temperature. Ymmv on how good you are with keeping up with the application.

### ⭐⭐⭐⭐⭐ Must-Have for 3D Printing
*by J***G on March 26, 2026*

An absolute must-have if you own a 3D printer and your nozzles aren't pre-coated. I own a Bambu printer, and none of their nozzles are coated for prevention of globing on the nozzle. I was having recurring print issues related to filament and stringing sticking to the nozzle, and then eventually depositing itself somewhere in my print. The VERY FIRST PRINT after applying this coating, I had substantially improved outer walls and ZERO filament on the nozzle. In the end, this will improve your print quality if you're currently having glob issues (and have troubleshot everything else), and at the very least, it will make your life easier in keeping the nozzle clean.
