Hi John,

I haven't found anything that sticks to canopy plastic that well. I've tried just about everything. What I do now is first wash the plastic very well with degreaser. That's degreaser - not dishwashing soap.

Then I mask off all but the the edge that will be glued and rough it up a bit with 220 sandpaper. Then I put a thin bead of slow epoxy on the edge and put the windscreen in place. I use tape or clamps or whatever to hold it. Sometimes I glue only the middle at first and allow it to cure and then come back and glue the rest.

Before any of this I fit the windscreen and remove covering from the model. Finally I do as McFlyboy says - clean it up with tape. Usually I cut a strip of electrical tape since it will conform better than most striping tapes that tend to come up quickly.

A couple screws near the end are a good suggestion, but keep them a ways from the edge of the plastic or it will crack.
