Hi guys just wondering is it better to put new sills in my ute,there is a minor bit off rust in the drivers side.Its only about two inches long and doesnt look to be anything major,should i change the sills or just repair it.The guy that is painting the old girl is stripping her back to bare metal fixing what ever is under the paint then repainting her.John the guy that is doing this for me has 40yrs experience and has done a good job before for me,said i will take him up to a month,is that standard.
