how much biaxl cloth/resin for transom job?

[BKROMKE]

Ready to start the process of re-coring the transom of my 81' scepter with 2 sheets of carbon core .75 inch and am curious about the amount of materials I will need for purposes of shopping for the best ballpark price.

I am estimating about a 5 gallon bucket of resin with accompanying hardener, and about 50 yards which would include some limited stringer and knee work back there.

What are your thoughts on how much resin and cloth is going to be needed. We are novice builders and will not be savvy in product use so I am fine with a bit of overkill. We'll also be working on other fiberglass issues moving forward.

Thanks for your advice!
