Whoa Whoa Whoa, I've never heard of a molding job that cost 300 Dollars. Maybe 300 dollars a fender. This is what I'm going to do. I'm going to do it my self. That's right im going to mold my entire body kit my self, and you can too, all you need is a lil courage and patience! Here's a really rough run down:
1: Sand to bare metal the area all bonding materials will touch
2: 3M makes an adhesive called somthing like 3118 Panel bonding. That stuff is ROCK SOLID! Essentially; glue the flare to the fender. Then quickly wipe away excess glue. (:::NOTE::: Always use latex gloves when working with any automotive materials.)
3: Use, a body filler (Bondo, Cuz, etc.) to smooth out the point where the flare meets the fender.
4: Sand, Sand, Sand, Sand, Sand, Sand.
5: When you think that you're done sanding, sand it a little more.
6: Primer and your ready to paint. You can take the whole car to the paint shop if you're doing a complete color change, or you can remove the fender and bring it in if you are staying with a stock color.
