I have extensive experience with Pallasites having collected them since the 1990s . My all-time favorite is Esquel. The Esquel had a clear coat finish applied to it and I saw one small rust spot appear. I removed the coating and polished it properly and it has been trouble-free ever since. Of course I live in the Mohave desert so humidity is not a problem.
The best advice I can give to a collector is to avoid rusters altogether. I learned the hard way and have lost thousands on improperly prepared Pallasites or specimens prone to rust. I pulled one example out of my safe several years ago and was dismayed to see that it had disintegrated. The only thing holding it together was the clear coat shell that prevented the crystals from popping out. The slice was actually flexible since the metal was all but gone. The clear coat held it together long enough for me to throw it in a trashcan.
A good specimen should not need any coatings or treatment in my opinion.
