Clear Canopy Insertion

This is one of the last items to accomplish in finishing a model and since the cockpit is a very obvious, upfront visual point of the model it is worthwhile to have the clear plastic canopy installed neatly.
You may already have a favorite technique but for those who don't, the following procedures offer a simple method.

• The fiberglass frame must be neatly trimmed by first using a cutting wheel to rough cut to the canopy frame lines. Then, use Perma-Grit files and small sanding blocks to fine-tune each edge. Sand the inside of the fiberglass frame with #80 grit.

• Paint the outside of the fiberglass frame to match the model. · Rough cut the plastic canopy to fit inside the frame. Use a grease pencil to trace the outline of the frame onto the plastic. Use PPG #320 solvent (or similar) to remove the grease pencil marks.

• In the case of the F-4 canopy shown, we will insert the plastic in 5 separate pieces. Carefully cut each piece 1/8" to 3/16" outside of each grease pencil line.

• Inserting the clear canopy in small sections yields a better fit and minimizes any possible distortion of the frame and how it fits back onto the fuse.

• Trial fit each piece and block sand the edges of the plastic with #80 grit to smooth the scissor cut edges.

• Paint the inside of the frame with flat black or flat dark gray. I like to use a catalyzed paint such as PPG Concept so that it won't peel easily when the plastic is glued in. Apply vinyl tape to the outside surface of the frame and use a small brush to apply the paint to the inside. Remove tape immediately and wipe away any bleed.

• Use one drop of Zap-A-Gap applied in 4 places around the periphery of each plastic piece to tack glue it into position. Apply the drop onto the fiberglass just next to the plastic then nudge it onto the edge of the plastic with a toothpick. It will bleed under the edge of the plastic but not onto the outside surface. Hold the plastic in position until glue sets. DO NOT USE A KICKER, it could damage the plastic. Warm breath will accelerate the cure.

• After each piece is installed, test fit the frame to the fuse to check that is has not been distorted. If it has, pop that piece loose and reset with better handling techniques.

• Use Pacer "Canopy Glue" applied with a small brush to the inside junction of the plastic and the fiberglass. Apply to the entire periphery of each part. This glue will dry perfectly clear - allow to cure overnight. Canopy glue is water soluble for easy cleanup.
