Summary: Bleeding knots - shellac 'em!

Yep, knots will get you every time.  I recently repainted my house
(see previous posting on paint removal techniques), but found that
I had to replace about 10% of the pine siding.  I knew about the
knot problem and asked around the paint stores for the sure-fire
cure.  The cheap and effective solution is shellac.  Sand your paint
off - down to the knot.  Put 2 coats of shellac over the knot, and 
repaint.  Works like a charm.  Oh yes - the same technique works for
water stains on sheetrock ceilings (where the H2O leak has made that
nice yellow spot).  Same thing is true - the spot will bleed through
new paint *unless* you seal it up with shellac.  Don't ask me why...
...maybe it's a law!
