I understand that purpleheart when subject to light fades to a dull brown. I am fixing ( as we say in Texas) to construct a chest from it and would like some help on an appropriate finish. I know spar vanish contains UV blockers but frankly I do not like the thick elastic look of spar varnish. I could thin it and wipe it on but I suspect it would lose its UV blocking if I did so.
Are UV blockers available seperately so I could add it to wipe on poly or an oil poly mix.
