Ziroli F4U Corsair PM.
Noticed some 'stress' cracks around the gear wells.
Decided to glass the gear wells which I, usually, do anyway.
It seems to work as I don't remember ever having a gear 'break' through the top of the wing!
Gear removed.
Some 'boat' thickness fiber glass from the local auto store cut to fit bottom and sides.
Zap finishing resin.
Let that 'cook' overnight.
