Sealing: Wax & Lacquer
封护：打蜡与清漆

化学着色膜虽稳定，仍会被手汗、摩擦与湿气破坏，封护是最后一道关键工序。①**蜂蜡**（最传统）：薄涂后烘枪熔融，软布抛光，留温润亚光②**微晶蜡**：更耐久、耐高温，适合雕塑③**丙烯酸清漆/聚氨酯**：户外或手持件，喷涂 2–3 层完全覆盖孔隙④**浸油**：钢铁发蓝件脱水防锈首选。**禁忌**：忌用含氨或酸的清洁剂后续擦拭（破坏膜）；封护前务必水洗去可溶盐并彻底干透，否则膜下起霜。
Though stable, chemical patina films are damaged by handling, abrasion and moisture — sealing is the critical final step. ①**beeswax** (traditional): thin coat, melt with a heat gun, buff to warm satin ②**microcrystalline wax**: more durable and heat-resistant, for sculpture ③**acrylic/polyurethane**: outdoor or handled pieces, 2–3 spray coats covering pores ④**oil immersion**: first choice for dewatering and rust-proofing blued steel. **Avoid**: ammonia or acid cleaners later (they attack the film); before sealing rinse salts and dry fully or bloom forms under the coat.
