body kit

Thinking of installing body kit & lambo hinges. Any thoughts on the what to use. FG, urethane, duraflez?? Price varies alot on hinges. Type of paint on kit?

Really depends on the body kit and eventually look you want for the car.

In general:

Fiberglass is strong, but can be heavy. One of the least expensive materials for a kit, and its natural rigidity allows for some very intricate designs. Also prone to cracking - so you have to watch for damage. Repair is a piece of cake for this material - most paints will stick well to and look good with fiberglass ONLY if you spend the time to prep the material first.

Urethane is much more flexible than fiberglass and has a natural durability (think rubber). Also like rubber, tends to be quite heavy and nearly impossible to fix. Can crack at low temperatures. Also tends to be more expensive

Duraflex is sort of in-between the two. Built on fiberglass materials, but the resin is more compliant - think of it as a mix of fiberglass, plastic, and flexible resins. It gives it the flexibility of urethane, but the stiffness of fiberglass. Still can crack, but not to the same extent as regular fibreglass. Sometimes you'll see this as a fiber-reenforced plastic or FRP - but Duraflex is more of a proprietary blend (more for marketing IMO).

thanks fishexpo101 for answering both questions. I will check the door out this weekend. Will look for duraflex or similar body kit.
