I came here looking for some help and answers. I got a few problems, one being a black Dodge truck with swirls and a few scratches. I found out by reading that washing my vehicles like my dad used to, bucket and an old rag, are definitely not the way to do it ...and, it probably caused my swirls. I'm working on that....but I no longer wash my vehicles like my dad taught me. I also moved to an area with extremely hard water which leaves some pretty decent water spots....and that's why I'm here...to learn from the pros. More "detailed" questions to follow.
