POR15 and cage nuts

[TexasKnucklehead]

I'm thinking of using POR15 on my floor and trunk pan, inside and out and am concerned about the cage nuts. I fear the coating might fill the nuts and could stick the nuts to places they don't need to be. If I put bolts into them, the bolts may become difficult to remove with the coating. I don't know how anyone gets the nuts and/or surrounding area covered without making a mess of it all. I don't want to have to replace cage nuts after it's painted.

Any suggestions are welcome.

I used POR15 on the underside of the floor pans and put bolts in the captive nuts and made sure I didn't paint them shut.

On the inside you should be able to do the same thing, being careful. I actually sanded away the slight surface rust on the inside of my floor boards, then primed and painted to match the body (or real close). That all got covered up with jute and new carpeting, so I didn't feel POR15 on the inside was all that critical.

I had just one or two more heavily rusted areas, and there I sanded and applied "Rust Mort."

just antisieze the bolt threads, put them in befores POR and remove them after. POR won't stick to antisieze.
