I'm at present plucking up courage to use matt polyurethane

Yuck. If you want a matt finish why not wax it?

Because being kitchen windowsills they're bound to be abused by stuff being
put on them detergent bottles, etc, which may mark them.

Or is wax proof against that - and is there a sort of initial applicatin
wax as against lokking after it wax?

If so I'll give it a try
