Most likely. However, it's just simple powdercoat... So it'll rust like that no matter what. Also looks like you live in FL so humidity, being near the coast, and summer heat/humidity will expedite the rust process. Do yourself a favor, and Wicked a favor as well. Just get it Line-X'ed. I know you don't want to pay for it now, but think about it in a year or two when it gets surface rust again. Wicked most likely won't cover it at that point and you'll end up getting it Line-X'ed mostly likely anyways. Just my $0.02.
