I am currently shaving an engine bay for a friend. I was wondering what could be the roughest grit I can under SPI Turbo and not have issues later on. I will set it in the sun a day so any shrinkage that has to happen, happens. I don't like priming over stuff in this state, but there are so many nooks and crannies, and filler to start glazing and finishing nicely.
