Agreed! $1000 is a drop in the bucket, body and paint around here will run you about 7-8k
I too had a "friend" do body work on my car. Took forever and the results to me looked ok, turns out when I got it to the paint shop...a lot more work had to be done. So what did I save in the long run? Not a dime, in fact it COST me MORE because a lot of the work had to be redone!!! The guy claimed to be a fiber glass expert (on my gnose prepping it for paint) what a mistake!). I just had the nose painted last week after the paint shop had to rework his handy work.
Bottom line 1st you get what you pay for, second if they don't have a spray booth or something that resembles one do not expect awesome results. I'm NOT beating on the guys that have done paint work in their garages (most of them are working on their own cars) but the part time, hey I can do body work and used to work for such and such shop...well there is a reason they no longer work at that shop.
There is a lot of wisdom, advice, experience and stories of success and failures on this board. Looking down from 30,000 feet at your project/body work, you're going to be disappointed but I can only hope for the best because you're spending your hard earned $$$$ on this car.
