Looking to polish my renegade siding. What is recommended and works? I'm tired of everytime someone touches it with dirty hands it leaves a print. A friend had his professionally detailed and he told me they used a sealer because his finish was so far gone? I'm hoping to use a buffer and get my shine back. I don't mind the work. He told me what his cost and it looks awesome, but I don't wat to spend that kind of money if I can do it myself.
