I use the FK1000 on mine which I really like the finish on and the durability is excellent.
Wax's i find dont last as long as sealents in terms of durability so i have never bothered with them.
If you are looking for something new to try, that give really really good finish with reasonable durability Try the Jeffs Acrylic range...
