Jul 14, 2006 · You can apply it over paint or bondo but it is only effective on bare metal. You can apply your high build primer or body filler over the self-etching primer but be careful it is not a finished product by it self. In other words you can’t apply it and then push the car back outside, it has to have a sealed surface over it, water will reverse ...
Omin MP epoxy primer can be reduced as sealer. Just reduce it 10% of total ready-mix. Some poly primer can be top coated directly, so you might just spray right on top of your sanded poly without sealer. Be sure to confirm it on the datasheet. The only problem to top coat directly on poly is that it will eat up more paint than sealer.
As far as your etch primer, I would wait for the time called for, to paint over it with other paints, not its own re-coat window. That might be 20-30 minutes, it will tell you on the can. Now you spray the filler/primer, and wait for the wet sand window, and wet sand with 600-800grit, to reveal the low spots, with a sanding block!

To do this you just spray an entire area (old paint and area sanded to bare metal) with primer and then wet sand or block sand until the old paint shows thru. This process "builds up" your low area. "Wet sanding" refers to sanding with your specially designed sandpaper wrapped around a skinny sponge with water running on your sanding area to clean away paint/primer from the area you are sanding.
Apr 02, 2006 · I have seen the stuff used in the past and have fixed stuff in the past with it on. In my experience I like clean bare metal, prepped, then either etch primered or Epoxied and a 2K urethane surfacer or sprayable filler over that. Underside no need for the surfacer unless your going show car award hunting.
Here is a 2K epoxy primer that is good for filling minor damage. It is direct to metal primer, a very high-quality type of primer. This primer is needed for areas of bare metal break-through, filing in sanded areas, and added protection/leveling over body filler. The duplicolor alternative is a 1K product that is of much, much lower quality.
