Review on 🔧 ACDelco 1152615 GM OE Gear Marking Compound - 1 oz by Brendan Thorpe

Better than Prussian blue! Auto Zone, O'Riley's, Stealerships & Napa (all my auto parts stores in my city) didn't sell it. They said you can order but it's $40. They only had blue shit. Get this for a more accurate reading when installing the diff and pattern checker. Get more on Double Triple Check. You don't need that crying sound like I do. Do it right, get yellow lube!
