scrape the lacquer of. the paint won't help. the UV-light can go 'through' the lacquer, and make it brownish anyway. unless warmoth's puts a UV-filter in the paint, though I seriously doubt that...

Actually, the browning is an oxidation process. The poly used for the satin finish is impermeable to oxygen, a necessary component of oxidation. Granted, there will be a small amount of oxygen in the wood, but once that reaches equilibrium with the oxidized product, no further oxidation will occur, regardless of UV exposure. I doubt this will result in any significant color change over time.
Patrick from Davis said:Just a chemistry note... Oxidation is the giving up of electrons or the gaining of positive charge by a molecule/atom, Reduction is the reduction of positive charge or gaining of electrons by a molecule/atom. Oxygen is not required, but it can be used in redox reactions. Sunlight, more importantly UV light, is higher energy light which can give energy to the reaction to allow it to move forward over the required activation energy. This could be for a redox reaction or the destruction/polymerization of molecules involved with the pigment or the wood. Not to nitpick but Oxidation and Oxygen get commonly confused. It is describing two very different things.
