Here's yet another question about properly seating screws in laminate
fibreglass.

Transom: fibreglass over wood. I have three 1/8" holes for the
transducer mount screws. Should I widen those holes, fill them with
West 105/205, let it harden, and then redrill the 1/8' holes to put
the screws into solid fibreglass with 4200?

If so, then what filler should I harden the epxoy with -- silica?

Thanks,

Jim
