Wonder how Superior Shield or Super Shield clear fluoropolymer spray by Shield Products would look? Fine sand then spray it on.
I sprayed Touche's chrome zinc cowl vents with it years ago. So far no pitting. Just sprayed some new cabin lights. This presentation shows it used on teak handrails. Have to try that next. http://www.shieldproducts.com/pdf/PP%20POWER%20POINT.pdf Dennis C.
