[Rhodes22-list] Re: CBtrunk fast dry hardener?

[Lou Rosenberg]

  Roger,
   I have a plan to install my alcohol heater below the boat with some 
sheeting to funnel the warm air into the (open ) trunk space and warm 
the interior  before mixing epoxy.   Warm up the  entire cabin and 
trunk area as much as possible including the use of a hair dryer or 
heat gun before mixing.  Then turn off the heaters and apply epoxy 
wait about one hour and begin heating again, just to be on the safe 
side.   I could postpone the epoxy work until spring but want to try 
this method first.
  suggestions?
  I know how flammable the vapors are and will not take any 
unnecessary risks.  The entire rear of my boat will be exposed for 
ventilation and  I could open my ports as well but they covered by 
the tarp.
  Lou
