I am looking for a product to replace zinc anti corrosive aerosols. I have two questions:
1. Did I understand the LEED criteria correctly? That anti-corrosive aerosols would be classified as Anti-corrosive coatings and thereby have a threshold of 250 g/L.
2. Is there an common substitute for this product available that would comply?
Thanks in advance!

The referenced Green Seal and SCAQMD standards do not regulate paints sold in aerosol cans, so IEQc4.2 does not technically apply to this type of paint. However, as LI#5581 points out, “aerosol paint applications are highly volatile and difficult to control,” and “using these products on-site is bound to add significant doses of VOC to the building.” VOCs in aerosols can undermine IEQc3 Construction IAQ Management efforts, so aerosols “should be avoided as much as possible” (http://www.usgbc.org/leed-interpretations?keys=5581).
Zinc anti-corrosive aerosols have typically been used to touch-up and repair damaged or uncoated galvanized steel. To protect IAQ, consider specifying brush-applied anti-corrosive paint (250 g/L max. VOC) in lieu of aerosols whenever possible. Construction IAQ Plans should address measures to protect IAQ when the use of touch-up aerosols is unavoidable.
