Recruit an electrophoresis master

This problem is serious! First of all, if you electrophorese the magnesium alloy workpiece into black, you can ensure that the electrophoresis can be closely combined with the black primer you want to bake. Second, the black primer temperature is too high. For example, acrylic paint is usually at 140+- 10, which is very high and easily becomes brittle and discolored. Third, rubber topcoat? Is it leather paint or something? The temperature is too high.

It is suggested that if electrophoresis is necessary, first coat a thin primer, then spray a powder coating for bonding, then a black primer and finally a top coat. It is best to configure it in the same paint factory, so as to make the layers of paint adhere and fuse. Note that the total thickness of these coatings should not exceed 80um, otherwise it is not easy to pass through the white dove.
