Question:

Is there a particular primer to use?

Answer:

Epoxy primer would be best, but any bare metal primer would be OK. Generally, the primer used is most dependent on the bare metal. For instance, aluminum is often recommended to be primed with more specific products.

Always check the label on the primer or talk to your retailer to ensure the proper product is selected for your surface. Also be sure to follow the specific instructions for the specific product selected.
