GluBoost Fill n' Finish Flexible Filler

GluBoost Fill n' Finish – Clear Surface Filler & Finisher for 3D Printed Parts Transform rough 3D prints into smooth, professional-looking finished parts with GluBoost Fill n' Finish. Originally developed as a premium self-leveling filler and finishing solution, this flexible, water-clear formula is ideal for eliminating layer lines, filling surface imperfections, repairing print defects, and creating paint-ready surfaces on a wide range of 3D printed materials. The formula remains flexible after curing and resists shrinking, cracking, and witness lines for a cleaner final appearance. Unlike traditional fillers that require extensive sanding and multiple applications, Fill n' Finish self-levels to create a smooth surface while filling gaps, seams, scratches, and print artifacts. Its long open time allows the material to flow into layer lines and surface imperfections before curing, helping reduce post-processing time while improving overall finish quality. Perfect for PLA, PETG, ABS, ASA, and resin prints, Fill n' Finish can be used to: Fill visible layer lines on FDM prints Repair chips, cracks, and print defects Blend seams on multi-part assemblies Smooth cosplay props and display models Prepare prints for priming and painting Create high-gloss showcase finishes Improve appearance of functional prototypes and production parts The crystal-clear, non-creeping formula stays where applied and dries with excellent clarity, making it ideal for both cosmetic and functional post-processing applications. Whether you're finishing a cosplay helmet, repairing a prototype, or preparing a display model for paint, Fill n' Finish helps deliver a cleaner, more professional result with fewer finishing steps.
