Guys, I have a few cracks in the nose of my 76TA. I'm not even sure exactly what material I'm dealing with, but what is the best way to fix these areas?

Should be blow molded fiberglass.
Sand a V grove in the crack only. Then clean with acetone or rubbing alcohol.
Mix resin and brush into V grove. Then add some fine hairs of glass mat and push
down into V. Let dry and sand and primer with 2K.

SEM 68422 is better suited for 70-73 flexible bumpers on Firebird /TA's.
I would not use it on Hard molded fiberglass as it will not reinforce the fiberglass cracked area and the crack will propagate as all fiberglass will do with cracks if not addressed correctly.

To each his own. Repaired many a Vette and I know because I had this same issue.
