On one boat removed a stringer where the "rounding" had been done with a polyester & fumed silica mix(i think). It was very hard an britle stuff, and it was suprising to see how cracked and partly loose from both the hull and stringer it was, adding only weight but no strenght.
So think its important that the paste/filler used in this application maintains at least some flexibility.
