This is a 7fl oz Bottle of Southern's Sorghum from Dave Brown Products.
Southern's Sorghum is still the best contact adhesive available for sheeting foam cores! It's simple to use! Just brush a thin coating on both the foam core and the wing sheeting; let both parts completely dry then press the foam and the sheeting together in position and it's bonded. Complete drying usually requires 30 to 45 minutes. This bottle is enough for an average wing and stab. Directions on the bottle.
