Better read a few other reviews first, POR-15 has the highest rate of failure and is almost impossible to dissolve if it fails and you want it gone, it peels off in big outlet blocking sheets. If someone held a gun to my head and forced me to coat I'd go for the Bill Hirsch stuff or the red stuff, both of those are ethanol resistant and go away easily with MEK if you ever change your mind.
I'm still most fond of bare metal if it's at all possible, there's a few ways to dissolve the shellac and muriatic acid followed by phosphoric removes all the rust, keep it full of fresh gas with the cap on and it'll outlive you.
