Re-coring the fuel tank floor hatch

[Zarkohl]

Great & timley post. I have a question, as I am getting ready to redo my fuel tank hatch. I noticed that you did not cut the access holes until after you glassed? I was thinking of cutting them first, so I could seal them up when I glassed. Interested to know your thoughts and/or what others have done. (i.e., Cut the access holes first and then glass or wait until after you glass?) Thanks, Jim
