Just a note. For any covering like Solartex or Stits Lite, when using an adhesive you only want to use it on the wood where your seam is, normally the leading/trailing edges of the flight surfaces or the corner longerons on the fuselage. You want the covering to slide over all the ribs/diagonals/sheeting/cross braces, etc when shrinking the fabric. It should only be secured with adhesive at the edges.
The one caveat to that is if there is a concave transition, in which case you usually need adhesive to keep the material from lifting off the concave surface when shrunk. For the cub, this would be at the transition of the fuselage to the vertical fin, although some people stitch the covering to the base of the fin and cover the stitches with pinked tape.
