What is your favorite method for fiberglassing wing center sections? I have used regular resin and finishing resin but this is my favorite to ensure a smooth, bubble free application.

After sanding the center section, mark off the location of the fiberglass tape.
Mask off the rest of the wing with tape and newspaper
From 12 inches away spray a light coat of 3M Super 77 adhesive on the tape area and let dry for about 15 minutes.
Apply the tape and position and press smooth. Don't wrap the tape around the wing, do it in two pieces.
Coat the tape with thin CA glue. It will spread evenly over the tape as you apply it. No need to spread it out.
The fiberglass tape color will change from white to balsa colored so you can see which areas still need CA.
Add some thin CA to the balsa area next to the tape to aid in sanding.

This takes a lot of thin CA and generates a lot of fumes so do it in a well ventilated area or best do it outside.
