    A Special Note about Email accounts!
    DO NOT SIGN UP USING hotmail, outlook, gmx, sbcglobal, att, bellsouth or email.com. They delete our forum signup emails.

    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

  • Returning Visitors

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

Deep pitting on engine

Yea, you might need the 180 to get down far enough to where the scratches are from the 100/wire-wheel.
You never want to go below 250, then you just don't get into the same problem area. And at that with 250 that is very rough.

If in the same (starting )position, I would use a palm sander with 150-250 depending on what you can do to keep it from clogging the paper to get to 99% of the corrosion off. Leave the rest for the remaining increasing grit sequence.

Thanks for the advice. I'll report back when the pieces start lookin' better.
 
The factory look is pretty close to 600 grit. It's actually a very fine "brushed" appearance with the grain in one direction.
