Nick, I got love for your Firebird.
From one inexperienced builder to another: you don't have to put into practice what others say (especially me!), but at least hear them out since many of them have been building longer than your or I have been alive.
In personal experience, following what these guys post in regards to basic prep work has shown substantial results in my last build. Keeping an open mind to suggestions, constructive criticism and self-improvement will make our future projects more satisfying in the long run. One bad building habit I have been trying to break is rushing. When I slowed down and took my time, the build turned out so much better. Hopefully the next one will be even better.
