Quest

No offense to OP but why buy paint from GuangZhou? (other than that it's possibly cheeper than buying locally?)

Besides: what sort of quality are they? are they lead-free? Alkyd paint or solvent-based enamel?

also: are you talking about Acrylic latex? Enamel? Polyurathane? Some paint are more "toxic" then other (such as automotive-grade 2-part polyurathanes) that without certain hazardous material permits or similar (for importation), I don't see you being able to get them in by following the protocol.
