I'm wanting to start the body work on my GT40 project before the weather turns colder. It's a fiberglass body with a few seams and a rather thin layer of gel coat. There are a few pin holes in the surface here and there. I'm used to working with metal and want to get this project off on the right foot. I have SPI epoxy and SPI high build 2K on the shelf. Platinum Plus and Platinum Plus glaze are my fillers. What is the best course of action to get this thing rolling?
