3. SURFACE PREPARATION 表面处理
A. Metal Surfaces
金属表面
(1) Aluminum and magnesium surfaces must have pretreatment before application of finish. Refer to the applicable overhaul instructions. If the pretreated surfaces have contamination, and are not unsealed anodize, solvent clean the surfaces immediately before you apply the finish.
铝和镁表面在涂漆前必须进行预处理。请参考适用的大修说明。如果预处理表面有污染，且不是未密封的阳极氧化，则在涂抹表面处理剂之前应立即用溶剂清洗表面。
(2) If the pretreatment is unsealed anodize (chromic acid, boric-sulfuric acid, or sulfuric acid anodize), the surface layer is porous and easily gets contamination.
如果预处理是未密封的阳极氧化（铬酸、硼硫酸或硫酸阳极氧化），表层是多孔的，很容易受到污染。
(a) Keep the anodized surface clean and dry. Use only clean, white, lint-free gloves to touch it. Keep away from oily, dirty surfaces.
保持阳极氧化表面清洁干燥。只能使用干净、白色、不起毛的手套接触。远离油腻、肮脏的表面。
(b) Light, non-oily surface particles can be removed with clean, dry compressed air, but dirty, oily contamination cannot be cleaned off. Remove dirty anodize and apply a new anodize before you apply the finish.
可以用清洁干燥的压缩空气清除表面轻微的非油性颗粒，但无法清除脏的油性污染物。请清除脏的阳极氧化层并涂上新的阳极氧化层，然后再进行表面处理。
(c) Do not let the new anodized surfaces wait more than 16 hours before you apply finish. If the anodize becomes older than 16 hours, remove it and apply a new anodize before you apply the finish.
在涂抹面漆之前，不要让新的阳极氧化表面等待超过 16 小时。如果阳极氧化处理时间已超过 16 小时，则应清除阳极氧化处理，并在涂抹面漆前涂抹新的阳极氧化处理。
(3) When pretreatment is not specified:
没有规定的预处理：

Let each layer dry, and sand it lightly, before you apply the last coat.
如果没有规定的彩色装饰涂层，则仍有必要涂上一层保护层。在第一层封闭层上再涂两层防潮防霉清漆，但这两层清漆要用甲苯以 2:1 的比例稀释。让每一层都干透，并用砂纸轻轻打磨，然后再涂最后一层。
(7) When a clear topcoat is specified, be sure to use a surfacer that agrees with the color of the wood.
如果规定的是透明面漆，一定要使用与木材颜色一致的表面处理剂。
