EN on Magnesium Alloy Castings

We want to do EN on magnesium alloy castings to give protection. There are generally two methods for doing this, i.e., the zinc immersion method and the direct EN method. However, we are a little confused about which method gives a better adhesion. Someone said the former while others said the latter. If you have any experience, I'll really appreciate your help.

For better corrosion & adhesion use the zincate & copper strike method.

Good luck
