Paint help quick

Used the degreaser just to make sure everything was as clean as I could get it. I'll probably sand down the areas that lifted, clean and reprime them and see if the paint holds. If that doesn't work I hate the thought of taking it to bare metal but may have too. The primer under those spots was sticking good yet so hoping round two sticks better.

Sorry but I still don't understand using degreaser after sanding seems like to me it would get in the pours of the primer and be hard to clean out no matter how much you clean it but I've been wrong before
