A small amount of acetone will work but it does change the strength and
porosity of the epoxy. A better idea would be to heat the cracks and epoxy
with a hair dryer. That will make the resin a lot less viscous without
effecting the cured properties.

A while back someone mentioned that you could thin epoxy with acetone.
I need to pour some into some cracks.I'm using System 3 epoxy. Thanks,

In a word, don't. Get some "Creeping Crack Cure," which is meant for what
you are doing.

If you are just filling cracks and joins to keep out the water (above the
waterline) I find Super Glue is much better than Creeping Crack Cure.

Glenn,
Do you have a target completion date on your sailboat?

*less* equals *more* ?

I would suggest you try heating the epoxy. Its viscosity
is very temperature dependent. Be careful not to overheat
the epoxy, no smoke! :-)

Use a heat gun and heat up the area you are treating. Air
in the cracks will expand and bubble up through the epoxy
and the when things cool the epoxy will be sucked into
the cracks.

I used to work in a paint locker for the coast guard I remember we used
to use a MOPOXY thinner for the 2 part mare island paints, Amron PSX
paints had their own thinners, The 235 series had the T-10 thinners.
There was pretty much a thinner assigned to each paint series there
should be one designated for the paint system that you are using.
