The current issue of Contact! magazine has an= article regarding serious damage to the epoxy fuel tanks on a KIS that the= author (Larry David) concluded was the result of using 10% ethanol fuel. &= nbsp;He didn=E2=80=99t specify what type of epoxy was used, and his respons= e to my e-mail to him was that he did not build the plane and didn=E2=80=99= t know what epoxy was specified for the KIS.

 

It is of interest since Chris, our rotary pow= ered Velocity friend, had a s= imilar nightmare with his fuel tanks.  Thought maybe you=E2=80=99d kno= w.  In Chris=E2=80=99s case it was Jeffco coating over EZ-poxy that pe= eled off.  In this case it was =E2=80=98whatever=E2=80=99 epoxy coatin= g over =E2=80=98whatever=E2=80=99 epoxy; and the fillets under the coating,= and the wing spar were also damaged.  Perhaps you are familiar with t= he case.
