I would say you have it figured out. I have never found anything that would cover brake fluid. Hopefully somebody else has.

If you strip it down to bare glass try covering the offending area with Talcum powder. It will draw out oils from surfaces that have been penetrated by oil. Acetone is a harsh solvent to use for problem areas. Have you considered a coating of Feather Fill type material prior to painting? Al W.

Better yet, use rottenstone instead of talcum powder as an absorbent. This is a little-known product, but readily available (just Google! the word).

We had exactly the same problem on our car in exactly the same area (using cellulose lacquer paint).

solvent pop may also be your problem , i would suspect that it may be the fluids from past spills trapped when you spray over especially if adhesion is a problem or you may be spraying too much too fast and not allowing the solvents to vent , remember to spray a thin coat then let gas off and then a second coat . Do not drown the area other wise you trap solvent and hence the popping is the solvents releasing through the substate when sufficient heat forces the issue . this can be seen in many paint jobs especially in the hood area . If you want to seal an area after priming use a sealer .
