The Astro Blaster kit uses contact cement for sheeting the wings. The
cement is of the water based variety. It is applied to both skin and core
and is allowed to dry. After this has occurred, the skins and core can
then be brought together. This is a little trickier, since you don't get
a second chance. Once the core touches the skin you can't separate them
without breaking something. The skins are just 1/32" thick so one
has to be gentle with them.
