Weak hood hinge springs?

the hood currently is factory (no scoop)
pin has not spun

dipped in chemicals at the local strippers......I think they use heat too. I will call them tomorrow and ask. I have had sets dipped previously....no issues

crap, I had a set of leaf springs dipped at the same time...we will see shortly on them.

make perfect springs for a lighter fiberglass hood

thanks for the replies.
Heat will kill off the stiffness of the spring. I've got a set of springs still mounted in the lower half half of the spring assembly if you're in need. I'm replacing mine with billet hinges and gas springs.
