I have 2008 black Saturn Aura (35K miles) that I polished a couple of years ago, and which sits outdoors in the blistering Texas sun all the time. The polish is (I assume) gone and the paint has begun to degrade a bit on the hood, trunk-top, and the roof. I have an electric polisher and 3 Poor Boy`s liquids left over from before (from their sample kit), but the polish is near empty. The paint needs a bit more grit treatment than the Poor Boy`s polish. I would like to order a Poor Boy`s product to bring back the paint surfaces that I mentioned prior to applying the Poor Boy`s polish. What Poor Boy`s product should I use?
