Metal Prep / Conditioner vs. Self Etching Primer

I have a bike tank that I am painting and on it's edges I have some chips down to metal. Otherwise the factory paint is mint. Of course my first thought was that I have to use a self etching primer which bent me because I had to buy more. Then I remembered I had some metal prep/conditioner that I was using to keep some aluminum from corroding after some restoration work I was doing.

My question is, bike tank paint aside, if I have a bare piece of mild steel whether it be a fender or anything else, is it ok, not ok, or "at my own risk" to use the metal conditioner/prep which is basically a very mild type of acid (what type I'm not sure. Maybe phosphate?) and then a primer/sealer or primer filler, instead of using a self etching primer on said bare metal? Of course all other preparations before paint being completed.

Thanks for the knowledge transfer.
