The Ship Model Forum

I needed to fill in a number of limber holes on special navy’s type II Uboat model. So I filled the holes from the inside with tamiya putty, pressing the putty through the hole until it completely filled the hole, unfortunately the putty shrank as it hardened, so it left a clear recessed gap around the perimeter of each hole even after I sanded and smoothed the surface. It is difficult to apply more putty on the exterior surface without ruining nearby surface details. Is there a putty that cures quickly and does not shrink as it cured?

A two part putty with a chemical hardener should be more resistant to shrinking that solvent based putties.
