Look into better technology. The issue with paint and powder coat is that they can't get every little area and end up rusting. They also can't stop rust that may have already begun to form. Auto manufacturers e-coat most everything. That's a terrific base coat. Completely seals the metal. Then top coat it. If you don't want to mess around, have it dipped in something like zinc phosphate or chromium. The gold metalcloak arms are actually a gold colored zinc phosphate. Chromium is even better, which is what I dip my metal parts in. It's pretty cool stuff. If rust attempts to form, the coating creates a chemical reaction that eliminates the rust. I live in MI and have bare metal exposed on my control arms. There's no rust. I never even bothered to coat them with paint or powder coat.
Op.. I have RR bumper. Its actually holding up well. Only rust is around the welds.

Cadmium or zinc phosphate are not something you can do at home. They are basically chemical plating. Cadmium is awesome, but some states such as CA don't allow it (it's safe for our use case).
I may be fortunate by being located near the motor city. I paid $90 to have 7 long arm control arms dipped. They can be painted or powder coated after, but I don't bother. Below are my arms post dip (I wanted gold to match the MC joints I used).

Happy Holidays everyone -
Been doing a ton of research on rust prevention for new powdercoated steel bumpers, and besides LineX / Rhino, how will taking a new bumper hold up with rustoleum etcher and truck bed liner hold up against rust? I want to address this before mounting on the JK.
Living in New England, between snow in winter and salt water air in summer, rust can be a huge issue - and I would hate to spend money on products that need constant maintenance. I don't wheel (sorry!), so I am just looking for the best option besides LineX / Rhino to save some $. Unless of course that is the only option -
Seems the self etching primer with bed liner could work. Doing this before bumpers go on, would I even need any prep work (ie sanding, roughing up)? Or just spray multiple coats of each?
Appreciate any feedback.

If you don't like constant maintenance... its probably best you just trade in the Jeep....
If you plan on wheeling it at all, it really won't matter what its painted with honestly, because it will get all scratched up anyway and then need to be touched up. I do maintenance painting twice a year, spring and fall. It's really the only way to keep the rust at bay in New England. Plus doing so keeps the Jeep looking clean.
