Here is the link to the post in my resto topic of the estimate I had gotten to do the core and transom in my vulture. Now this DID NOT include any real body work or any paint/gel what so ever.

It was just over $8k and im going to say that 90% of it was labor costs. I decided to do all the structure (core, stingers, transom) work myself and so far I am right about $1100 in materials but lots of time into labor. I had a huge amount of help from Chet (77viper) and that helped big time in the labor department as mine was a nightmare from the word go as it was previously repaired by someone and they used all the wrong materials and made for a lot of extra work.
I had never done any real fiberglass work until this and I can say that its nothing close to being as hard or intimidating as I thought it would be. Some of it does suck like the actual grinding when taking the old core out to get it ready for the new core but I think thats mostly due to the fact that fiberglass equals lots of itch if you dont suit up for it right.
