I use some carbrite products. The dealer that goes to the local body shops stops at my house. I don't buy enough for him to stop every time he runs this route because I only detail my own cars but when I need something I call him and he drops it off at my home. He comes every other Thursday.
I use their dressing called SHEEN on my show car for all the fender wells and under hood plastic and rubber pieces. I have not found a product that even comes close to this one
At a show this gives me the advantage over the competition who use APC or tire dressing on the wheel wells.
I hope no one in Indiana who goes to shows reads this.
