jmk,
Thanks for the idea. I actually already have a chip guard product that I bought for this purpose. But I have not used it.
Rust on my wheel wells starts on the very thin edge of the metal. Even with the metal on each side protected with POR or similar, rust starts along that edge which is too thin to get much of any kind of coating on.
That is why I am thinking about something thicker. POR has a putty in a tube (POR+filler probably). It might stay in place. But seam sealer is really cheap and seems to work elsewhere in exposed location, so also thinking of using that.
Problem with stone guard, could be getting it off if and when rust reappears and repainting is needed
Had thought about the stoneguard tapes, but shape of wheel well edge is quite complex and I could not see how to apply it.
I am sure I am not alone in this. Maybe I have repaired those edges just one to many times
