I'm not a glass guy and I don't play one on the internet. But I have seen the rear skin job first hand though on my last V20. IMO If done right it will be just as strong or stronger than not cutting either skin from what I saw.
The guy that did mine didn't cut the skin, he ground it down to nothing all the way around, close to where you have yours marked. Then the outter skin came off and he prepped everything for "glue and screw". The difference was my wood was good but the idiot that did it before me DID NOT BOND THE OUTTER SKIN TO THE WOOD.
Got the outter skin glued and screwed back on, then its just a matter of building up layers over the part that was ground out in order to re-attach the skin. Then some fairing and sanding and done.
It would seem to me that just going in from the top it would be harder to get the best bond. But like I said, this was my only experience so I haven't seen other methods in person. When he got done you couldn't tell it had been touched and it was very solid. Solid enough for the new owner to hang a 200 johnyrude.
Wish I had pics but I don't.
