Abstract
We consider the spin polynomial invariants for bundles with c_2=2 and c_1 = K_S + 2nk a rational mutiple of the canonical divisor on a Dolgacev surface. It is shown that the chamber structure can be controlled so that the polynomials give diffeomorphism invariants of Dolgachev surfaces of the form q_S(n) = a(n)Q^2 + b(n)Qk^2 + c(n)k^4. The two leading coefficients are computed.
