Humbrol Decalfix is a 125ml bottle of model glue decal. It is used with decals to improve adhesion and help conceal carrier film. To use, shake before use. Cut the decal and soak in the solution for approximately 1 minute until the decal starts to come away from the carrier sheet. Brush a small amount of solution onto the desired area. Slide the decal from the carrier sheet onto the desired area using a soft brush. Remove excess Decalfix solution with a soft brush and gently dab with tissue. Leave to dry for 6 to 8 hours. The decal may wrinkle once applied, but will then sink into any curves/panels and harden.
