Thanks for all your compliments. Especially Scottwax. Coming from you, wow!
As to the owner not letting it get bad again... he knows better. He helped me work on it, so he knows what went into it. After we called it quits, he joked that he would take it to the bay wash once it got dirty and go after it with the brush. He almost got a PC in the face!
That van was bought from his father, who supposedly never ever washed it or waxed it once in it's life.
Why people won't take care of their vehicles, I'll never know...
