Enquiry on some RPs as follow:
1, The first's for steel parts and its film should be colorless, transparent, dry to the touch and not any tacky at ambient temperature after spraying or dipping 4-24 hours later; The salt spray time should be over 48 hours (5% NaCl, 40 centigrade, continuously spraying).
2, The second's also for steel and its film should also be dry to touch and not any tacky, colorless and very transparent to keep workpieces' original bright appearance or be replaced with a chrome-like appearance, also its salt spray time should be over 48hours.
3, The last one is for gear's (of auto gear-box) rust protection, must meet Ford's requirement (the relative documents need to
