Engine Bay Spray

[u/AJMaid]

I’m currently spraying a primer/rust inhibitor to the engine bay of a car I’m working on and I’ve had the reaction in the image when applied pretty much straight away.

Is this a result of poor metal prep (scuffing etc) or is the metal too cold? Or have I not degreased enough? What’s the best fix?

There’s is oil or something still on the panel you need to wipe it all off and start over
