What Z32 said. On an understeery FWD chassis like the A32 you can countersteer and hit the go pedal, the tail should come back in line. In general, the more throttle you apply the quicker the rear will recenter itself. What you DON'T want to do, on the other hand, is back off the throttle and try and catch the rear with the wheel. It is doable but you want to shift as much weight to the rear as possible.
Trust me, I have been out ebraking mountain roads in the rain more than a few times.
When you want the tail to stay out, you lay off the gas. When you want it to fall back in line get back on the throttle and be prepared to straighten the wheel quickly.
