Thanks guys! I forgot how frustrating the prep stage can be. I paid a lot of attention to the top of the radiator support, since that what people's eyes tend to see. Just when I thought I had the surface smooth enough, I'd see something and have to sand & re-primer again.
Greg, I used Rust-Oleum Satin Black for the major surface areas. I knew not to use a gloss, semi-gloss, or flat black, as I was looking for a matte finish. I hope I do not regret not using a high temperature paint. Those shock towers can get hot down by the factory headers. A few pieces (like the bracket for the windshield wiper motor) will be painted in glass black. Once I have everything buttoned up, I will go back and touch up the fasteners in either satin or gloss black.
I'm not so sure I'll get much done today. Instead of working on the car, I'll be spending some family time with Jack on a Sporting Clays range in lower Delaware.
