The previous thread was too old to resurrect, so...
I had great results with a shipwright application of Propspeed last slip, and a disaster a few years before that with a dodgy mob doing the job. I'm considering DIY this time. It looks pretty straightforward and an easy way to save a few hundred bucks if I stick to the instructions.
Any suggestions of do's/don'ts from those whao have done it would be much appreciated.

Cheers, Graeme

Preparation is everything. Have everything to hand so there is no delay. Timing is fairly critical. Work fast!
