Restore 72 OUTER ALUMINUM grill help

[custom10nut]

If you’re refinishing the WHOLE grille shell, use either Aircraft Stripper, or Old School Oven Cleaner.
Be careful with either of these and it’s best to use them outside, for maximum ventilation.
When you’re done with the polishing, use Ever-Coat to protect it.
There’s a very detailed Thread on polishing the Grille Shell and Side Mouldings, just find it in the Search bar.
