Okay since you guys were waiting to see it skinned I spent the day working on the rear spoiler ...I ended up using .050" 4130 steel, it added more weight than I wanted but not enough that the lid wouldn't stay up on it's own, I'll adjust the hinge springs later to help it out a llittle more. Anyway this thing is sturdy as can be ...I still have to finish off the part where the two frame pieces come together ,that shouldn't take more than 45 minutes but I ran out of time today, total invested time so far is 11 hours but I really expected to be spending 3-4 weeks on this project so It's not that bad of a job. I'm really glad that I stuck with steel and was able to fully weld it to the deck lid . Enjoy
