Kframe, engine bay, front suspension questions

I brushed on some 2k epoxy since I have the same reservations that you have regarding spraying. This protects my metal, gives it a clean look, and can be lightly sanded and sprayed with more primer, or top coat by the new owner (which is what I plan on doing when it is ready for paint). And, since it is 2k, hopefully more durable than rattle can.
