Wow, I don't think I understand much of what you just said. I get the idea but remember _ I know very little of fiber glass and molds.
I "assume" the wax is to keep it from sticking when I cover the outside of the fuselage? What is PVA?
I don't want to waste your time as I think I need step by step instructions and I don't even know what products - wax, PVA, glass, etc to use.
I get the idea I want to make a replacement section of the fuselage then when I cut out the hole my replacement piece will be bigger than the hole then I cut it down to fit the hole exactly so there is no seam.
If you have time I can call you or we can email back in forth but again I will need step by step guidance on this.

So, in your case, if you WAX 3 times and PVA the section of the fuse you want to duplicate,( I) put bondo on the section to create a throw away mold to layup a section of the fuse to cut a "hatch" out of. Then take your new molded and trimmed "hatch" and use it as your cut guide. Then you have a clean fit and cut line. Make Note to adjust for glass thickness when on final install of internal support for "hatch'
Hope that helps
