I'm finishing up my car, this weekend and I have a question to toss out to you guys. I painted my hood hinges body color and now I need to paint the springs. I think if I try to do them body color with base coat clear coat, the paint will crack when the hood is opened and closed a few times. what type of paint should I use or does anyone have a better suggestion for what I should do.

If you paint your springs with BC/CC and they will not crack. BC/CC is flexible enough to be used on urethane bumpers which flex a lot more than springs. I put a piece of flat steel slighly longer than the closed length of the springs to keep them streched so that I could paint in between the coils. Worked great! Dan

Whatever you do with them, I think you need to stretch them a little while painting, to ensure than paint gets in between the coils. Pehaps you could build a little jig to hold them stretched slightly.

best way to paint hood hinges

I am a production manager in a powder coating plant, I would powder coat the hinge and springs because of flex in the hinge it can crack. I painted cars for 40 years and have used flex additives to help but nothing beats properly aplyied powder coating, expecialy when it is free. you can do it your self in an oven in your yard.

The problem with powder coating is that the color won't match the hinge. Hood hinges extend less than an inch, and when that is divided into the number of coils on the spring, the deformation is negligible. Having said that, I wouldn't paint throttle springs because they would crack for sure. Dan

When I painted my springs, I just hooked one end on the floor jack and other end on the lifting arm to make it easy to stretch em out. I sandblasted em and sprayed em with DP90 and they havent cracked yet :thumbup:
