I just swapped out my stock front bumper for one from AtoZ Fabrications.
My new one weighs about 45 pounds, but my stock one can be lifted with only three fingers! They are fairly useless bumpers, which is why aftermarket bumper sales are so strong.
Regarding Powder Coating, Zach offers a new, textured finish that is quite nice. I have my front and rear bumpers and my rock sliders all done in it; very cool looking and tough.
However, there seems to be a swing in opinion here on JF that POR-15 (I think that is what it is called) would be better since it protects just as well and can be touched up easily.
Also, many seem interested in having their rock rails and bumpers Rhino Lined.
I would NEVER, EVER spend the bones needed to Powder Coat, Rhino Line or Line-X a TJ,YJ or CJ stock bumper since they are worth less that the cost of the coating.
However, using a rattle can of Rustoleum Hammered would look great and would be super cheap if you have to stick with the very thin, almost useless stock bumpers for a while. They are okay, and many never change them out. But they are very flimsy if you look at them carefully, and if you choose to go off road a lot you will need to change them at some point.
Save your money for something that will make you happier in the end.
