Painting over Duplicolor Primer

[T-Bucket Bob]

I want to spray feather-fill primer surface over duplicolor primer on my frame. Should I strip the dulpicolor primer off, or just spray over it?

Thanks, T-Bucket Bob

I am no expert on paint but I think you should have used etching primer on a bare metal frame.

Epoxy primer is what I was told and used on all bare metal. But I see etching or epoxy is recommended depending who you talk to. I don't think there is a clear better choice...

There are epoxy self etching primers such as PPG DP-90. That may be what was used. I would ask someone who works where you purchased the primers or will purchase. It's usually best to use products from the same line that are engineered to work together.
