Just my .02¢ worth but I wold replace it. I had a Canton and never worried abut the Gold color. When the rock picks and such got to much I would just take a rattle can and spray it gold again. I had one other pan that was welded on another car and about 2 months later it started leaking from a tiny split that was starting at the end of the weld. After that I felt much more at ease with a new pan.
