I agree!  I'm as frugal an SOB you'll ever meet but finishing sheetrock is right up there with doctor visits. 

  Can they somehow computer match the surrounding roof paint color so I don't have to repaint the whole car if I do this?  My roof is not a standard 240Z color.

Screws are out, more adhesive goo stuffed into the holes. Clearly welding the holds shut is silly.

I will be entrusting the roof shaping to a real body man. That thing is no place to learn sanding technique. I dont do my own drywall either....

You and me booth! I'll take a dime size dent, try all the proper techniques, I think, prime and go what the heck!

I think it's like art, some people got it and some don't. I don't!

One more trick I forgot to mention.  I put a thin (1/16") layer of bondo on the inside of donor roof BEFORE I cut out the patch section. I wanted to support the shape and make it stiffer while I handled and mounted it. Made a huge difference to stiffness.

I used about a 3/16" notched trowel that you use to apply tile adhesive evenly to get a nice even coat of bondo, and just knocked it flat with a wide putty knife to spread it out. Some people call me thin skinned....

I've had mixed results with computer matching.  According to one paint tech I dealt with, the darker the color, the more difficult it is to get a good match.  Metallic content adds to the challenge.

My car came painted with an unidentified, non-stock dark green metallic, so getting a match has been a problem.  I ended up asking a high-end restoration shop for help and they put me onto the specialist paint supply shop that they use.  I removed one of my Z`s inspection cover panels and gave that to them to use for the paint-matching.

Perhaps you can  try the same approach.  Find a resto shop that works with high-end customers and high-end cars, and then ask them who they use for their paint.

Thank you Namerow that is very helpful.
