seacast transom

[jonesg]

I just got through doing my transom w/ seacast,
its interesting stuff.

Use unwaxed poly resin,
promote it with DMA .05% by volume.
Add some cabosil to prevent the resin from draining out of the mix. A texture like thick corn syrup is a good starting point.
Store this a couple of days, catalyse with bpo (benzoyl peroxide is available at ace hardware for using with bondo putty) add chopped fibre and its ready to pour.
Just follow the seacast directions.

dimethylaniline (DMA) available from chemical suppliers, hard to track down but its out there. It must be used with BPO or the resin will not harden, its in bondo but bondo isn't too usefull.
