About 2 months later it was starting to peel especially near the header and was getting dime to quarter size spots. It at first did look better than just the other untreated panels

the ppg dau75 never came in a rat can. stuff is very good for alum and mag but like i said i do a test panel when dry it is very tough. i use it on intakes it s hold up was good on vintage wheels for M&A casting it was fastastic i used it on many rims all the indy light wheels i did along with many others i did for ted at the time

Orange hand cleaner works to remove water spots, grease and grim from aluminum and chrome.

Microscopically water spots are actual corrosion or etching. Everything I have found requires elbow grease. I have also found that most of the clears I tried left a milky look.
