I have done several European trips, including southern Spain in august 2018 when we saw 45 degrees on the outside air temp, we drove up the Sierra Neveda mountains that day, and not a hint of overheating.
Cheers.
The oxidation process should hopefully protect the areas from further corrosion.
It’s not in a highly visible area anyway as it’s behind the engine block etc so I won’t be removing it. If I did, the oxidation process would start again at some point.
I carried out some cosmetic repairs on the front suspension uprights last year even though there were only a few spots on them. Something that I did notice though was large flakes of paint that had come away from the off-side rear driveshaft which I then rubbed down and treated (well worth checking).
Good to hear that the shrouded bonnet vents on your car haven’t caused any overheating issues. You’ve certainly put them to the test in that 45 degree heat!
