I disagree with Mr. Stiffy.
Many many cobra builders have never built a thing in their lives ... until the cobra.
The purchase of a Cobra kit is that one accepts they are going to do/make/build/fabricate/invent all manner of things quite foreign to most non trade folks.
It's a project, like building a boat/airplane/house and one should attempt whatever they want to fulfill their sense of achievement.
Like Stiffy, I have seen some horror stories. In most cases i find the horror also extends to what you cant see. ie. Suspension not refurbished, shocks and springs from the wrecking yard, poor drive train alignment, lousy wiring etc.
That just reflects the nature of the builder. Oftenwise, that builder is as proud of their creation as a builder with a triple digit showpiece.
On the other hand, I have seen some excellent work done by non practical/non-trade type folks( like school teachers)
. It is just attention to detail and patience that is the key. Ohhh and ask heaps of questions.
I encourage folks to attempt the paint job. If after the first coat of primer one realizes it looks crappy, not much money is lost.
My hint for painting: Use a blunted hacksaw blade to apply bog to curved surfaces. Specially the tops of guards.
