What product should I use to protect these outdoor projects?

by Dani Moore
I have two outdoor projects I want to seal and protect, a glider that I repainted to match my pantry and the ramp to my THOW (Tiny House On Wheels). It needs to be transparent and I would love to be able to add a clear non skid something to the ramp as well.
The Glider
The ramp (with Christmas lights!)
