Looking for advise, tips, tricks, etc on re-contouring the deck lid on my '69 H/O convertible build. How malleable is the zinc(?) body? Will it bend a bit before fracturing? I am amazed by the diecast cars you guys build and hope there's someone who knows their way around a diecast body who will share their knowledge and can keep me out of trouble and on point with my project. My sincere thanks in advance for you assistance!!!
