Hello i just have overlay some pieces from my bike and i left the bike to the out and in some places the carbon blow up with the sun any idea why what i did wrong? and sorry for my english 
I’ll be the first to answer since I’m Greek and I understood what u’re talking about :P:P:P
the reason for the separation of the carbon from your plastics is between the following:
- the resin didn’t stick properly. Did you sand it before laying the carbon?
2.High temperature - Greek Sun
3.Bad quality resin
4.Resin and plastics not compatible
Hope this helps…
What was your surface preparation procedure? Is it possible that air was trapped between the carbon and the surface which later expanded due to the heat from the sun? Possibly a chemical reaction with residue on the surface?
