I would spend the few hundred extra to buy a nice steel hood, then all of these issues become moot. You are really opening up an expensive can of worms. You could spend $1,000-2,000 on bodywork to get that hood the way you want it. Then it will behave oddly when you get the car done and you will always be subject to cracks, blistering from the heat, and fear that your hinges will break it.
1969 Firebird 350 Coupe, Rust free Texas body, formerly brown, now a TA clone with quality spoiler, latching hood and TA wheel; 1969 GTO Convertible Expresso Brown/Parchment(currently painted red). Both numbers matching. My first love was a Cameo White 67 326 Coupe, bought back in 1983, at the age of 17, for $1,200. Been hooked since on PONTIAC! Working on a 67 400 ragtop for customization-Gulf Turquoise/Parchment/400/4 spd! My winter project!
