A dewshield alone will not totally stop dew formation. Insulating the OTA will also extend the dew free period. But if dew formation conditions are heavy enough, then dew will form, and you will need a way to prevent dew from forming or drying it off. And of course, there will also be nights when dew won't form.
I like it. Will consider in future, thanks.
