Corrosion is showing along the bottom lip of the tailgate on my P38 - again.
Last year I buffed it back to what looked like clean metal, then primed and painted it but the area has continued to oxidise and it's looking as tatty as ever.
The back bumper is also discoloured with grey/brown streaks which, I believe, could be coming from the corroded panel. Other than replacing the tailgate, is there a solution to the problem, and what is the best way to restore the bumper to its original black?
