Need some help from the paint experts please? I’m switching paint guy’s do to the first one’s life got in the way. I found another guy who I seen some of his work seems to be perfect. My car is now in epoxy primer sealer painted by the first guy. I showed the car to the 2nd guy and he said for me to sand it all down because I should have used etching primer. I thought the epoxy primer sealer was better. Someone please clarify this for me. I tried to read other post about this and it’s confusing. I’m not selling the car so I’m not looking to take any short cuts. Thanks.

I have painted many cars over epoxy primer/sealer.
Epoxy primer is a good base to start from.

Is this car ready to paint or does it still require bodywork? Body filler shouldn't be used directly over or under etch primer as the acid in it could affect the filler. Everyone has their preferences , and I prefer epoxy.

epoxy on bare metal is best,sounds like the second guy is behind the times.
