Looks good centerline, but I think you are confusing epoxy and etching primer again. Etching primer isn't 2 part, okay it has 2 parts, a vinyl? resin/ zinc, and acid, but its not really a 2k product, and you really don't want to paint over it without using another primer first-most tech sheets I've seen give strict warnings against painting directly over them. Maybe you could paint over them or some manufactures say its okay after allowing plenty of time for the acid to leave, but most say its a no no. Etch primer usually has very little build and if you apply them heavy at all will be running all over the place.

Epoxy on the other hand is 2k . It doesn't contain an acid to etch the surface, its more like a glue, so surface should be sanded for adhesion, but much better then an etch primer and less chance of leading to any problems with other products or down the road.
