Epoxy filler, water proof?

I repaired some damage to my hull the other week with epoxy filler. The RIB now needs to live in the water wail I have some things done to the trailer. With the cold outside I can't flowcoat the hull yet.
Is bare epoxy filler waterproof? I can put a small amount of flowcoat over the repair and set it with some heat until the time comes for doing the whole hull if need be but would rather wait till I can do the whole hull.

If you've got room I'd roll the boat off onto an old mattress or even the grass rather than drop it in the water for any length of time if you are worried.

You could try rendering the underside of the boat and the giving it a couple of coats of Sandtex.

Just an idea.

Thanks Nasher,
Not got the room to store it like that. Will try asking friends and family if they can spare some space for a couple of days. Otherwise it's the marina. Looks like I'll have to put a temp coat of topcoat. Balls!

if you used EPOXY filler it should be waterproof - its actually more waterproof than gel/flow coat. We used to use plastic padding filler (not epoxy based AFAIK) for temporary repairs to sailing dinghies left in the water - with no issues.

Epoxy will withstand petrol and other solvents along with strong acids so water shouldn't be a problem.............

Should be fine with epoxy filler. As far as I'm aware its the same as epoxy resin but with a bulker/filler in it?

Copper coat is just epoxy resin with copper filings in isn't it?
