Powder Coat vs POR 15

I will say that these bumpers and nerf bars and such that come powder coated are probably not done to the standards that a small shop will do, but those giving advice above are correct, once rust gets under it, there is no stopping it.

I have a For ranger that came from the factory with powder coat on certain suspension components, they are now rusted way more that they would have been had they been painted.

where I work we tried power coating on the frame of a piece of equipment , it looks good for a year but didn't take long to start chipping and cracking from flexing and then it started to blister under the power coating and when we tried to remove it for repair it was a lot of work, I personally wont do power coating after seeing this

I find if I drive fast enough for long enough, every part of my chassis eventually get covered with a nice coat of oil which prevents any rust.

Everyone has their own preferred painting method. Personally, I media blast the parts and apply alkyd red oxide primer. After curing, I sand the part prior to the top coat application. Prep, prep, and more prep is the key to any lasting paint job.

When applied properly, alkyd enamel primer such as Rustoleum, Majic, and Van Sickle will outlast your rig. It's really all about your budget and technical ability.

I've used KBS products,  I like them better then POR15. I like there Rust-seal, still needs a uv coat if in sunlight but they have good options there as well.  They come in lots of colors and etc.  Great stuff.

I used ZERO-Rust on my extra frame several years ago, hanging our in the weather it looks great, no new rust anywhere on the frame. Has some pollen on it from the GA springs over the years. A coworker had a PWC trailer that was powder coated tubing from the builder, saltwater useage rotted the frame out from under the coating after a few years and it collapsed.
