If you have time, try one good coat over recommended primer and let it sit for a month.
 
Slow drying

I did not use Rustoleum on my RV interior, but have used it on several giant scale RC models that used gasoline over the years. A lot of their paints are alkyd enamel and dry slow. You might want to give you test samples a week or so to dry before abusing them.
