bonding cycle wings?

[baz-r]

If I want to bond my grp cycle wings to my metal wing mounts what is the best way of doing it.
Stickaflex or laminate in with grp where two ideas I had in mind.
I don't want to drill holes to make nice spider cracks but I don't want them to fly of either.
Also I hear of people coating the inside of wings to stop stone damage etc does. Everyone do this?
