    Hello Gentlemen,

    I’m detailing my 79 308GTB, and I have a series of questions:
    Where the battery compartment is are two coolant pipes (aluminum), the acid from the battery corroded one. I tried to polish it out but made is shiny, any ideas on how to bring it back to the original finish?

    Thanks Guys,

    Chris.

    I doubt a corrosive chemical will yield a satin finish like the factory did. You might want to try a pollish of some sort then a flat clear coat to get the results or paint it with an aluminum restoration paint called "alumiblast" from Eastwoods in the states. they sell restoration products that replicate metal finishes.

    It's Sodium Hydroxide, aka 'Lye', sold for plumbing problems, you have to make up a fairly strong solution using hot water.

    If you start with fairly polished metal, it will leave a satin finish very near to the OEM finish. Good chance the OEM pipes were cleaned with a hot caustic during mfg, which is what left that finish.

    Use rubber gloves, eye protection, etc...
