interior paint question

[KRAUSEGB]

I HAVE BEEN SPRAYING SEM SELF ETCHING PRIMER #39683 ON THE INTERIOR PARTS OF THE COCKPIT.

I WAS READY TO PUT ON A PRIMER SEALER AND FOLLOW THAT WITH ZOLATONE 20 SERIES TOP COAT, SO DECIDED TO CLEAN THE SURFACE A LITTLE BECAUSE IT HAS COLLECTED SOME DUST OVER THE LAST FEW MONTHS WHILE DOING THE FUSELAGE.
USED LIGHT DETERGENT AND WATER.-----BIG PROBLEM---

THE PRIMER BEGAN TO FLAKE OFF--ENDED UP REMOVING MOST OF THE PAINT, AS IT WAS COMING OFF JUST BY RUBBING IT WITH A RAG AND WATER.

WHAT HAPPENED??

ANYONE HAVE AN IDEA WHAT I DID WRONG AND HOW TO FIX IT?
I REALLY NEED SOME HELP ON THIS ONE.

GARY

Did you sand first

Self-etching primer on this smooth a surface will not likely do what you want. I think you will find you need to scuff it with at least scotchbrite pads to get anything to hold.
