Congrats.
Please forgive me for what may very well (but unintentionally) come across as patronizing, as you probably did something like what I mention here as a matter of course.
But, in the event you did not go beyond washing and add something like Ballistol —

I, too, trailered my GRiSO in nasty weather:

Anyway, my rollerized but sad GRiSO was pummeled by salt and worse for almost 800 miles of turnpike.
After I washed it, I tried to find every vulnerable spot where corrosion might be an issue. About a month later, I saw that I’d missed one. Nasty. Yet, everywhere else, doused with Ballistol as I generously did, has stayed just fine.
Enough.
Best wishes for miles of smiles on that beyoootiful GRiSO.
