Hi I am stripping surface that off the bulkhead of my moggy. I am not going for a show car just one that is presentable. Do I need to use etch primer first on the hard metal? Or can I use high build primer? I want to used the build primer to help cover some of the undulations.Thanks Jed

This link is not my tutorial, but pretty much the path I follow to build a substrate for paint. Lay down a coat of epoxy first if you want maximum weather protection. www.redpowermagazine.com/forums/topic/64890-step-by-step-hood-restoration/The Everfill 4:1 high build polyester primer is rated for direct to metal use, and can be sanded to 400 grit and painted over, so maybe a shortcut for what you want to do? |

Ive always put epoxy primer over bare steel, then high build. I agree that is the best path, but the OP seems to be looking for a quick and cheap solution and still have some material thickness to smooth over ripples. One thing that needs to be understood with the 4:1 is that it needs a gun with a large orifice, the stuff is thick. As always, go on line and read the material data sheets before you buy. Learned the hard way that pot life is short! I have to wonder why the OP would not do a skim of filler if he cares at all about the final results; if the panel is in good shape most of it will come off anyways. High build primers are good, but they are no substitute for filler if there is any depth to a ripple or ding. |

etch or epoxy first
you might find epoxy has enough build to do what you want , and is a better product than etch

Thanks for your help, it’s not a show car, more oily rag, I don’t want to use filler as the bulk head has lots of recessed areas that are hard to get access too, I just wanted to rub back surface rust and key the surrounding paint but try and minimise the slight imperfections in level that the newly clean areas will produce. Thanks all for your help.
