Klasse has an
AIO product
KAIO and the SG which is the sealant.
Zaino has an
AIO product ZAIO and either Z2pro for lighter colors or Z5pro for darker colors as the sealant.
Now if you want to do multiable coats within 24 hours, zaino has a product called ZFX which you mix with Z2 or 5pro. You put 4 drops of ZFX into a mixing bottle with 1 oz of either Z2 or Z5pro. Shake for 90 seconds. 3 coats max within 24 hours.
IMO zaino Z5pro will give you the best results on darker colors.
