I am looking at some rust that needs fixed in 3 . One is a small hole where the rocker meets the floor and has rusted out a 1/2 inch by a 1 inch hole .It has also rusted the lip where the weatherstripping goes in the door opening. Then back by the tail light on the inside of the Quarter is another . I don't have any welding equipment . So should I pay someone or just fiberglass it ?
