What kind of primer do I use

[240znz]

Hi all,

Now in full swing in stripping the zed. Finding little spots of surface rust that I will need to pay attention to. I'm killing the rust as I go but I need to paint it with something.

Being a complete novice at any painting, what type of primer do I use?

Well if you can't get all the rust off then I suggest using a product called POR-15. You can paint it over the rust and it will seal it in forever. If you did manage to get it all off to bare metal then spray some kind of "self-etching" primer. The self etching stuff will actually etch the metal and make for a better bond on all later topcoats. Almost every name brand paint system has one, just pick the brand you plan to use through the whole project (I say this because switching brands from like DuPont to PPG may cause problems later on). Good luck

DO NOT USE POR 15 FOR EXTERIOR SHEET METAL!

Although it is a great product for painting over rust, it has a tendency to set very quickly after being painted and NOT flow out. This lack of flow out will show up on your final surface paint as uneven shine, and hence will make your paint job look awful.

You WILL need an etching primer in order to do the first primer coat on bare metal. If you use any other type of paint for the first coat you can count on it blistering or flaking off later. You can top self-etching primer with any one of various surfacers, whether high-fill or light and then go to final paint. Heck if the body is straight enough you wouldn't even need to go to a fill primer, but you MUST first shoot etching primer.

Hope that helps.
