: I haven't built a kayak yet, but have used a small inexpensive kerosene
: heater in my basement garage were I repaired motorcycles in my spare time
: using all sorts of solvents and chemicals. I do have a co sensor in my
: shop and having used my heater all day and all night preparing for a race,
: never had a problem. Like others I would allow some fresh air in every now
: and then. I also started it on high went upstairs until things heated up
: then turned it down low and went to work. No strange smells- No headaches-
: No problems.

A problem, not mentioned in this tread is that oil, propane or kerosene types of heat can put hydrocarbons in the air that can cause a comtaminated epoxy surface, more blushing and possible white clouding. This is quite common. Electric or other dry types of heat are best, especially when you plan to have a clear finish.
