Epoxy etching

[s.vannostrand at kodak.com]

Thanks everyone for the suggestions.  Here's what I did.  The longevity of 
this repair is TBD, but all your suggestions gave me confidence that it 
was as good as anything:
1. Thoroughly agitated it in 99% alchohol and brushed with old toothbrush
2. Sprayed with brake cleaner (this is really effective at powering out 
all the little grime)
3. Heated with heat gun.  No additional oil came out, but paint blistered.
4. Brake cleaner again immediately (just in case heat gun liquified 
anything) - glad it wasn't flammable.
5. Dried for 1 hour
6. Repaired with west epoxy with no thinning.  THis epoxy was thin enough 
and I figured that captured thinner can not evaporate and would weaken the 
bond.
7. Gently heated to make sure epoxy penetrated well.
8. Reinforced seam with a new layer of 3.2 oz carbon fiber

Sanded and repainted blistering.
