I have used a few corroless products and they seem good so far, Primer, Corroless S, and is nice to apply, quite high build and as such takes a while to dry properly.
Top coat corroless chassis in one, dries quick and gives a nice satin finish, but I find it hard to get a good finish with the brush. But maybe that's just me.. Sprayed is better if an option.
Corroless RF16 gives a better finish I find, is gloss and available in most colours.
I have also used Rustoleum combi colour on a good few projects over the years with some good results.
