Not that it matters to most people, but originally the engine bay was painted semigloss black, except the firewall which was body color. So yes you canHi! I'd like to go with base/clear on the body but doing that in tight or heavily contoured areas like the engine bay or even the dash seems difficult.
How do you block those areas to get a shiny end result? Should I just use enamel? I know I'd still have to sand that but is it more likely to give me that super glossy finish? Can I single-stage the engine bay and base/clear the exterior?
