All the other steel parts are coated, including the nutplanes and don't cause dissimilar metal corrosion.
Go ahead and leave those tie down rings installed and then try to remove them in a few years and report back. It will only get worse over the life of the airplane.

I see many that are concerned about corrosion live in some humid and wet environments. Out here in Phoenix with a hangar I haven?t seen any corrosion issues on my Cherokee (29 years here) or my RV-12 (6 years). However, I used to worry about glass transition temperature when I had a WAR FW-190 at summer air shows sitting on the ramp.

Glass transition temp?

Everything?
Yeah, everything is coated. Go ahead and believe that, if you want. What about the stainless firewall and all the aluminum rivets and angles attached? And how about those cad played bolts? You know, the ones where the cad playing is removed during the tightening process... Look at a standard washer that has been previously tightened. You will find the cad plating has been removed.
Point is, dissimilar metals are a fact of life. Preventing corrosion can be as simple as applying a light coat of grease or anti seize to the threads...

Doug,
The older fiberglass epoxies lost strength if overheated. The critical temp was called glass transition temperature, and 30 years ago people tried to avoid painting dark colors on the fiberglass so it wouldn?t sit in the sun and lose strength. In Phoenix we can actually fry an egg on a dark surface on the worst summer days. GTT was something you had to think about.
