: Snow is in the forcast for tomorrow!

: Time to move the boat inside ( or try to ).

: So will the off-gases explode when they come in contact with the furnace or
: what? Oil furnace if that matters.

Epoxy doesn't have a lot of volatile components. It smells, so obviously SOMETHING is evaporating and reaching our noses, but usually epoxy resin is not diluted with solvents which would escape during the time the resin polymerizes and hardens. What ever does escape is probably as concentrated as the oil in the air after you fry a batch of chicken or french fries -- certainly enough to make the house smell (usually a good smell) but nowhere near enough to cause a problem with a furnace.

Polyester resin, on the other hand, is loaded with volatile components. Even so, I've never heard of them causing problems.

On still another hand (I need someone to lend me this hand because I've talked myself out of the only two I own) solvents from varnish, or possibly polyurethane, were responsible for a raging fire which destroyed the local bowling alley several years ago. The business was closed while they were refinishing the lanes, and it is believed a spark from some electrical relay ignited the fumes. The explosion blew dozens of bowling balls out of the building and into the parking lot. Parts of the building traveled over a mile. Fortunately, none of the workers were hurt.

So, resins are not that bad, but the varnishes you should should take care with.

I would worry just a bit about any oil in the air landing on the epoxy while it was setting up. Microscopic amounts of oil in mixing containers have been blamed for a "Fisheye" problem in the past. hopefully your furnace's combustion chamber is well sealed and no evaporated heating oil (or carbon monoxide) gets into your living space.
