What do you put on bare metal before primer?
To properly prepare new metal surfaces, use mineral spirits to remove grease and apply a rust-inhibitive primer before painting. For painted surfaces that are in sound condition, remove dust with a clean, dry cloth, de-gloss the surface with light sanding, and wipe with mineral spirits to ensure good adhesion.
Should Bondo be applied to bare metal or primer?
Bondo should NEVER be on top of anything but 32-grit prepped bare metal, if you want it to stick and last. You can, however, use glazing putty on top of primer sanded with 80-grit. Do not slap Bondo onto a smooth painted surface, it is not going to stick very well.
Does body filler go on bare metal or primer?
The short answer is filler companies suggest it needs to go on bare metal, and epoxy companies suggest you put filler over epoxy so they can sell more of their product.
How do you prep bare metal for painting?
The first step in painting metal is to thoroughly clean it. The metal might look and feel clean, but any grease, oil, dirt, or rust left on there will prevent the paint from properly adhering to the surface. Avoid using water to clean metal; instead, use a solvent such as acetone.
What is the best primer for bare metal?
Epoxy primer works best on bare metal and is recommended for newly-fabricated metal parts or those that have been fully stripped. You can also apply primer surfacer or filler over epoxy primer to get rid of any minor imperfections and to create a flat surface before you paint.
Can you paint bare metal without primer?
Metal that is exposed to the elements requires a primer before it can be painted. In the home, metals that are commonly found include wrought iron, galvanized steel, and aluminum. Aluminum products do not hold paint well without primer. It will also oxidize if not sealed properly.
Should Bondo be applied to bare metal?
What you are working with needs to be properly prepped BEFORE you apply any body filler. Do not slap Bondo onto a smooth painted surface, it is not going to stick very well. The paint should be sanded off, to the bare metal, and then apply the filler. A 36-grit to 180-grit surface is ideal for body filler application.
Should I prime before using body filler?
Before adding any filler, you should get the metal fairly close. For small repairs, you can bog directly over the bare metal. If the repair is larger, or you’re looking for a longer-lasting job, apply a base coat of epoxy primer before laying on the filler.
