Self etching primer

[FOMOCO_1546]

I recently applied self etching primer on my bronco which was 100% bare metal. I've replaced almost all the sheet metal. My question is, Should I, or could I use a primer surfacer over the self etching primer? Thanks

If you used the rattle can self-etching primer, I would take it all off and use some out of a air spray gun. To do it right, you really need to find the system of paint you are going to use and then get the self etching primer and filler primer that are compatible with the system. That way, all the chemicals will bond correctly and you will have a really nice paint job. My experience with rattle can etching primer is that it sucks. My .02.

Yes you should and use the same brand recomended by the top coat manufacturer. After all of the work you have done don't go using a rattle can now

I used Dupont 615s primer mixed with 616s converter. Not a rattle can. Thanks

I'd still use a surfacer. It will make it alot easier to wet sand out any imperfections. Then primer, wet sand and shoot the top coat.

Had same consideration. Reluctant to have too much primer/paint build and encourage chipping. Objective was for optimum mechanical adhesion and durability.<br>So, I settled on Dupont Variprime self etching primer and Imron top coat.<br>Where corrosion was evident, parts were sand blasted and/or wire wheeled to bare metal. Otherwise, old paint was well scuffed with 220 grit.<br>Have finish 2 rigs this way. One is going on 20 years and the paint is holding up well.
