So considering I'm not going to strip this to bare metal, Just wash the crap out of it, sand any areas with rust, but that's about as much prep work as I'd like to do, is there a product that I should lean towards that will better adhere and last without a hardcore prep job?

Kinda like how Plasti-Dip, it'll still adhere even with less than ideal prep work. However I'm not using that, just an analogy...
