While detailing my truck this past weekend I found a chip about the size of a dime on my roof.It also was rusted. I have some Duplicolor paint for my truck paint color.I just sanded the rust then sprayed it.I did this temporarily to stop the rust.Can I do this repair or leave it to a professional? If I did the repair,what is involved?

 

Not sure about what you have on your roof but I have had excellent results using Dr. Color Chip
