Strip, clean, acetone, heat then use an oil resistant high temp paint and high temp clear. The paint will nick, chip and scratch easily.

Be sure to use automotive 2k clear. You can buy it for a spray gun like auto body shops do or you can get it in a spray can from spray max off Amazon. If you don’t use 2k clear coat your paint won’t stand up to chemicals at all.

Pics of the frame would help. If its already a painted steel frame, new paint will adhere to the old pretty good. No sense in peeling that away. Just use a steel brush and some solvents to flake away the loose stuff. If you have an abrupt transition from paint to bare metal....you can hamd sand with a 320 grit or so to blend it together for a smooth transition.

Then clean everything. Any number of solvents you could use...acetone or denatured alcohol are cheap. Use a microfiber cloth because it wont leave particles behind like paper towels or cotton. Spot primer the bare spots and then you can paint.

Be patient and try to do several light coats. A dozen "misting" coats will resist chipping better than 3 heavy coats. When you paint, hit the hard to reach areas first. Thats about it. Make sure to wait for a nice day too. Low humidity and 60 degrees and sunny.

I know you said no, but Power coat depending on color you're looking to do.

I paid $100 to blast and powder coat my frame black on my project bike. I told them i wasn't overly picky on the black, just gloss and asked what is their normal black they do batch runs of for people. They showed me the color and i was good with it so they just put my frame in the next batch getting black.

For $100, i could not have done a better job. They masked off all bearing surfaces, threaded holes, etc. Killer job for the ridiculously cheap price.
