As I said in an earlier post, I have no doubt that the interior will never look as good as one with a liner, but I am encouraged by the basic improvement over the original finish which showed every imperfection like bulkhead tabbing, voids, ridges and the texture of the outer lamination. I think there will still be some slight wavyness on some of the surfaces when I finish. I guess I could fair this out with some addittional effort, but "I have miles to go before I sleep".
Whether body filler is adequate for the job, I guess time will tell. It would have taken lots of epoxy to do this job. I have tried to apply a very thin coating beneath the foredeck where the deck flexes readily (enough to just fill the texture of the cloth). I think if the filler is going to fail, it will be in this area first.
Here is a picture of the rear salon with most of the filling completed:

There is a before picture of the same area at:

Its sort of difficult to see from the picture just how bad the painted surface was before.
