Thanks all for the many excellent suggestions..... you've given a lot
of different options based on personal experience.

I'll be trying most of them. Won't replace the shutters unless
the surface has deteriorated, they are only 10 years old

But the thoughts of paintable versus non-paintable... and
long warranty makes it worthwhile to dig up the old paperwork.

I think these were 'builders edge' from Home Depot.

Thanks again for all the responses, suggestions. It's a
pleasure to work with you guys !!
