The inside of the nutserts looks gross also, but I've decided that its the anti-seize that we put on the stainless steel bolts that hold the flares on.

The real concern here, is that if the corrosion eats through the outer ring of the nutsert, it will allow the nutsert to spin in the JK's super thin sheet metal. That would mean I'd be in a situation where the flare is half on and half off with the stainless bolt halfway out. Then I'd have to cut it off and drill out the nutsert.

Any way you slice it, you need to make sure to prevent that sort of problem rather than deal with it.

Here's my solution.

Im going clean the nutserts as best I can with a waterbased degreaser. In this case, its going to be "simple green". I think it will be gentle on my paint, while cleaning the nutserts.

Then once they are as clean as I can get them, Im going to POR-15 them to seal out the elements.
