Finally found a "real paint store" that sells Benjamin Moore exterior

Store employee asked what I was planning to paint over -- oil or
latex. I replied that I didn't know because it was already on the
house when we bought it, and (unlike with many of the interior paints)
the previous owner hadn't left any of the exterior paint.
Store employee asked if the existing paint was cracking. I said that
it was, and she said, "Then it must be oil based, because latex paints
Is that true? So if I prep properly and paint with a 25-year warranty
latex, the only reason to repaint within that time would be that we
get tired of the color?
It might be possible for latex paint to crack, but I have never seen
that. The clerk was probably right. Latex, in my experience, peels
with a flexible,
filmy character. Latex flexes a little bit on expanding/contracting;
oil less. That is why it appears it might be oil.
Is this an old home? Wood siding? Moisture damage? I would expect -
and I am not a house painter - that if you scrape all loose paint,
clean it properly, prime, it would be ok to use latex. Make sure it is
dry when you paint, not in hot sun, and follow all the label instructions.- Hide quoted text -

I was a pro painter, I just painted my garage door last fall after
alot of great scraping over old cracked paint and its cracked again
today. I used sherwin williams best paint. My original coats are shot,
I should have stripped the doors.
What would you suggest for stripping a whole 100 linear feet or so of
8-ft high plywood siding? I had thought of using a power washer then
(after a week's drying time) priming any resulting bare spots, but it
sounds as though you would recommend something more drastic than that.
Hardipanel (pre-primed) over the plywood? Instead of the plywood? Or
just attack the existing plywood with one of those 3M paint-stripper
wheels (like a super-aggressive version of ScotchBrite)?
