Thank you for your responses. I think I will stick to the silkspan and dope finish.
What paint would you recommend?
And what can I use after butyrate dope to seal and fuelproof the finish, and stop the constant shrinking caused by the dope?
Or could I use something instead of butyrate dope to apply the silkspan?
Silkspan on a trainer?!! Hmmmm.....Longevity might be a problem unless you are an accomplished pilot.
Let me suggest that you take a look at the Model Research Lab website and find their polyester tissue. The material looks and feels similar to silkspan but is much much stronger than silkspan. It will rip like silkspan but boy you have to work at it. Weight is similar to medium silkspan but takes less dope to fill so you end up with a lighter product
It is applied with nitrate as if you were covering with silkspan (no water tho, sorry) and is heat shrinkable like woven polyester coverings and films. In my experience it offers the best of all the worlds. It fills quickly to boot (again with nitrate) and is ready for just about any paint (thinking spray can types like Krylon here). It is a good idea to use primer first over the filled tissue and sand lightly. Then shoot your colors
