Nice discovery

[peter]

I have the optional aluminum engine bay panels and have a hard time keeping them clean. After doing some research on Club Cobra I learned about an etching chemical called "twin etch" available at Napa. It leaves a nice patina -- smooth no shine, raw, brutal and no trailer queen. Best of all no more water spots!

Thanks for the info Peter.

I have also used WD40. Just spray it on a soft rag and wipe the area down. If you also have stainless steel kitchen appliances, loan your WD40 to your wife. It works wonders on SS.
