I got some Mother's Mag and Aluminum Polish awhile back for my old civic valve cover. I did wonders for my valve cover.
I was wondering how well it would work with a stock exhaust. So I took my mom 2002 Accord and polish the stock exhaust with Mother's Mag and Aluminum Polish. One hour and 30min later, this is what I got.
My old civic engine.
If you want to stick with your stock exhaust but want to add a little shine to it, go buy some Mother's Mag and Aluminum Polish and polish away.
