"name": "Why should I apply RustSeal before NuMetal Epoxy Putty?",
"acceptedAnswer": {
"@type": "Answer",
"text": "Sealing the metal surface with RustSeal before applying NuMetal prevents rust from forming underneath the epoxy putty. Rust forming below NuMetal can cause it to lose adhesion and pop off over time. Always seal with RustSeal first for a permanent, rust-free repair."

{
"@type": "Question",
"name": "How do I prepare RustSeal for NuMetal application?",
"acceptedAnswer": {
"@type": "Answer",
"text": "Allow RustSeal to fully cure for at least 24 hours, then scuff the surface with 320 grit sandpaper before applying NuMetal Epoxy Putty. This provides the mechanical adhesion needed for a strong, lasting bond."
