In a year and a half to two years I am planning on replacing several body panels on a late ‘70s American coupe that could see up to daily use. This raises several concerned regarding the doors and the hood. The doors are fairly long and the hood is around 169mm long and 148mm wide. Since I’m in the planning stages, I figured I would ask now, rather than later.

I am planning on using your vacuum infusion process and will be finishing the body panels for a stock look, but much, much lighter.

As I stated, panels are going to be finished and painted so, should I concentrate on finding a source of carbon fiber wide enough for the entire hood, or should I use two pieces? If I’m using two pieces, how should they be laid for best finish and strength?

Ultimately, I want this to a nearly direct replacement, so... How many layers of carbon fiber should I use?

At what width or length should I consider using a core?

Should I consider using a core or simply make the parts entirely out of carbon fiber?

I’m planning on making an inner frame of steel to tie the hinges and latch for the door together as well as provide side support in the event of a crash. I’m also planning on embedding captive nuts to provide attachment points for the hood. Is the technique and epoxy in your video appropriate, or is there a better method?

I appreciate your consideration and any advice you can provide.

Thank you.
