i havent tried many products.. this stuff called black again has made me happy.. goes on very easy and gives a really nice shine, after heavy rain i noticed a couple of streaks where water ran out of the doors, but they were easy to touch up..... theres are some close up shots in my gallery from the show i entered, thats what i used to prep for the show and i got lots of compliments on the cladding there.. 5.99 at strauss discount auto...
heres a link to a desc. of it http://www.autogeek.net/blackagain1.html
