HI Sailormon,
here you can see my results by using an coated polyester and an synthetic resin varnish:

+ durable glueing (stern / bow), or after scratches
+ hot shrinkable
+ not hygroscopic
* shiny finish, people do not realize it is an SoF
-relatively heavy, applyed many layers of resin
- i think it could be more durable (e.g. scratches)
so i decidet to try next time an uncoatet ballistic nylon and applying an urethan coating - we will see,
i am very interestd to hear (and see) about your experiences.
