                                            November 8, 1995

Securities and Exchange Commission
450 Fifth Street, N.W.
Washington, DC 20549

To the Members of the Commission:

     This opinion is submitted in connection with the Registration Statement on 
Form S-3 (the "Registration Statement") being filed by PPG Industries, Inc. (the
"Company") with the Securities and Exchange Commission under the Securities Act 
of 1933, as amended, in respect of $500,000,000 aggregate principal amount of 
Debt Securities to be offered on a delayed basis.

     I am Senior Vice President and General Counsel of the Company and, in that 
capacity, I, or lawyers in the Law Department of the Company acting under my 
supervision, have examined such written documents and corporate records as I, or
they, have deemed necessary or appropriate for the purposes of this opinion.

     Based on the foregoing, I am of the opinion that the Company has been duly 
incorporated and is validly existing as a corporation under the laws of the 
Commonwealth of Pennsylvania, and that the Debt Securities, when duly 
authorized, executed, authenticated and delivered, will be legally issued and 
will be binding obligations of the Company in accordance with their terms.

     I hereby consent to the filing of this opinion as an exhibit to the
Registration Statement. I also consent to a reference to me and to this opinion
in the documents constituting the Registration Statement.

                                            Very truly yours,

                                            /s/ Guy A. Zoghby

                                            Guy A. Zoghby
