I have a question about painting my car. I recently asked about what type of paint I should use on my engine compartment and (I think) single stage acrylic urethane was recommended. If I go with this how do I blend it with the BC/CC I plan to use for the body? This car was painted from the factory with the fenders in place, which means part of the fender would be painted with the engine comparment. How do I meet the two different types of paint and still make it look good?
