The deed has already been done, John.  

I deliberately went for the slower-curing version, to get myself enough pot-life - I'm no good under pressure, like to take my time.  Pressure = stupid mistakes.

Viscosity:   cps 80
Pot-life:     10-20mins
De-mould: 2-4hrs
Shrinkage: 0.007in./in
Shore D:    70

    Looks good Stuart. If you are casting a body using a single piece mould ie slush casting then a shorter pot life is desirable otherwise you are holding the mould and moving the resin around inside for a long time. I f you are pouring into two part moulds no problemo or into open detail parts moulds no problemo either.

After ten years or so of casting I still make mistakes, have failures, have spills and splatters…… and make a mess but my success rates are usually high.

I'll be using open moulds, John.  

.........And thanks for your input.
Also, thanks Joel for pointing me back to Smooth-On.
