Hood hinge "after."
Now here is the problem with my electrolysis. I never got much off with electrolysis alone. I had to follow up with Evaporust but the results were amazing. Evaporust alone wasn't as great either but when combined, the electrolysis seemed to loosen things and then the Evaporust took it right off.
That limited me to such things as brackets, etc. Largest thing I ever ran was the battery tray.
