I thought I would fess up to a real blunder in hopes of saving my fellow builder some time and heartache.
I had some extra PPG Aluminum cleaner and conditioner laying around sooooo I thought, why not use it to clean up the parts before I lay down my coat of primer. There is only one problem, Im using Sherwin-Williams etch primer for all the internal parts. Without even thinking about it I cleaned up all the parts with red scotchbrite and the aluminum cleaner, which come to find out is really acid etch. After priming the parts and allowing it to dry over night, here are the results.
Comes right off with your finger nail..
The tech rep at SW gave me a fix of a different primer. But the old adage of never mixing brands and materials sometimes can be a costly lesson..
