This info has me concerned I have
a kerosene heater in my garage in
was bought new last year . I keep the garage door open a bit
to keep the fumes of the
epoxy and the carbon dioxide levels low.but you can still
smell the fumes.
I have never heard of this before has any on else .My thoughts
are do I stop
the building and redo all the work .God I hope not. Or is this
a very rare accident with little
chance of duplication.
I do sand all lay-ups completely between
all application.my be from now on I will use a
cleaning solvent on all parts before every lay-up. But I do
think a new heater my be on
order anyway .
Also does any on else notice that after sanding the
glass it turns a shade of green
in the sanded area . And alpha poxy turns more yellow. this
happens over time .
