Nothing wrong with doing your own install. Drop me an e-mail when you are ready to start and I'll give you some tips on what materials to use and the methods I use when molding a body kit. My cougar was my first body kit install and since I've built 11 cars. I'm doing an 01 Cougar, 00 Eclipse, and an MX3 right now. Just make sure to have patience and some practical garage skill.
