Actually coating the rings with CA is a pretty smart idea.
I sometimes coat weak balsa fins with CA. Stiffens them up real good.
A very simple ejection baffle is a course steel mesh (like Choir boy pot scrubbing pads. NOT like SOS pads or steel wool, that will burn)epoxied to a centering ring and placed somewhere between your engine and chute. It acts as a flame arrestor.
What burns chutes is the flames and hot chunks from the ejection charge. Chutes can wistand the hot air alone for the fraction of a second they are exposed to it.
Elaborate baffles re-route the the gasses through several 90 degree angles for basically the same effect.
One note of caution. Install any mesh several inches ahead of your motor tube. (the mesh does get hot and can damage the end of your motor tube if left in contact with it.)
Another common method is Nomex pads. They attach to your shock cord via a button hole and rap around the bottom of your chute when you put it in the rocket.
I recently baought a set of these for my low and mid power rockets from our very own Flying_silverad (from his Ebay site)
and am very happy with them.
