Sand Epoxy Fillets & Fix Laminate Bubbles: Prepping SpaceshipTwo-ish for Paint!
In this installment of our SpaceshipTwo-ish model rocket build from Advanced Construction Videos, we tackle the crucial prep work to make your rocket smooth, strong, and paint-ready. With all assemblies complete, watch as we first sand down the epoxy fin fillets using a round metal file, carefully smoothing out any lumps or irregularities to create clean, aerodynamic surfaces that look professional and perform at their best.
Then, after applying primer (full painting tutorials available on our site), we address a major issue: air bubbles trapped under the paper laminate on the fins, which weaken the structure and create ugly bumps. Learn our proven fix—carefully cutting small slits into the bubbled areas, wicking in thin superglue to re-bond the laminate to the balsa wood underneath, and pressing firmly to eliminate voids for a flawless, durable finish. Your rocket is now truly ready for topcoat painting and launch!
These practical techniques ensure your builds are not just functional but visually stunning. Perfect for anyone refining their rocketry skills.
