Hi Wooders, as the biggest part of my hobby is restoration of vintage models i always seal my wooden hulls with Ezekote water based resin and a layer of lightweight glass cloth.
This not only seals the hull but strengthens it as well.
Being water based it is odorless and dries very quickly, usually ready to sand and paint within 35 minutes. And doesn't seem to have problems with any type of paint.
Hope that you find this information helpful, cheers Colin.
