[Rhodes22-list] Bill Davidge ... before painting...

[Michael D. Weisner]

Ed,

Please follow the directions of the manufacturer of the paint.  Boat wash 
products may contain waxes which is no good for paint.  Also, while acetone 
is usually good as a preparation, it is by no means universal.  Some paints 
require a toluene (or the older version, toluol) solvent wash.  Remember, 
this stuff is all REAL TOXIC.  Chemical respirators, gloves and paint suits 
MUST be worn.
