tanks on his rigs. He got it from some guy in Kentucky. All I know is that the solution separates and you have to keep shaking it. It worked real well and I was able to polish it up using just a terry cloth towel. I then followed it up with some Mother's metal polish. Pats300zx told me he used some (0000) steel wool with Brasso Metal polish and then followed up with some mother's polish to buff it out. Phuong posted some pics awhile back of his DT stillen exhaust. The stuff my Dad gave me is probably comparable to Brasso. It took me about 2 hours to clean up everything using alot of elbow grease and patience. If you have anymore questions just email me.
