POR 15 for my rear T-case and driveshafts?

I was going to paint my rear first and i have some POR 15 left over would it do the job? or is there something better?

it would doe the job, i would not reccomend painting the tc with it though, after it dries it would be hard to get the tc apart in the future if u needed to, i have my axle painted with por 15 as well and it has held up great and looks good still after almost 2 years, i owuld just use a good aresol apint for t he driveshafts thoeugh i dont see why u would not be able to use the por 15 though good luck

What would you use on the tcase and tranny?

Why would you want to paint them other than cosmetics?

I'm pretty sure both casings are aluminum so they're not going to rust.

Just give them a real good cleaning and they should be fine.
