Re: READY TO PAINT !

Alan,

   Be careful when spraying interior paint.  This was discussed a while
back and probably archived on psubs.  But, I have a fear of spraying any
kind of flammable paint inside a hull with only small openings to the
outside.  This goes beyond just the breathing issue where you need air
pumped into your mask etc.  If there were a spark with a high density of
spray it could be another Apollo disaster with both explosion and fire.  I
am not a paint expert by light-years, but perhaps brushing, or a water
based paint might be safer.  If I were actually going to use flammable
paint and spray inside a hull I would probably use massive ventilation and
wear clothes that are not known to create large amounts of static charge.
Years ago, when ether was used in operating rooms, they had restrictions on
"All" clothing worn due to the explosive nature of the ether.
