Mylar!

[Sparrow]

Just wondering what type of adhesive should I use to glue the mylar sheet into the canopy... and to anyone who is using it, if they had any problems with it (ie. melting). tia.

I've used Mylar as reflective material, but never inside a canopy.. though I'm sure it'd work.. I was just worried about the heat melting it.

You can tack it in place, rubber cemement, all kinds of things..
