Removing runs is something that every painter has to deal with. No matter how many years you put in no matter how many cars you paint the fact is you are going to have an off day and cause some runs.
Really this is not the worst thing that can happen but it does delay you and if the run is in the color coat it will mean stopping the work until you can break out a uv light and cure the work for sanding or maybe wipe down the area with reducer and feather it …

All cars will eventually need some love but before you grab your sandpaper and buffer there are some considerations you must take into account when working on older vehicles.
Many people get confused about what products they should use to restore and maintain their paint finish.
