So if you blasted a part to clean metal and put a coat of rattle can zero rust on it because it is going to be quite a while before you are ready to actually prime or paint then what would the next step be when you are ready to actually prime and paint? Why would someone do that you ask? Well not all of us have a HVLP turbine or air compressor at home to easily be able to spray a primer on things as they are cleaned to bare metal. I have a basement full of parts that I have sandblasted and they are sitting in a single coat of rattle can zero rust until I actually purchase or rent a HVLP turbine and spray gun.
