I doubt it would hide the scent.
The "rotten vegetable" smell from camping propane is added as warning by the manufacturer for when propane is leaking.
Propane, naturally, has little to no scent.
Green Gas is scented from previously unscented propane... so what you're saying to do is to add perfume to "rotten vegetable" propane... which will still smell like ass.
Ár skal rísa, sá er annars vill
fé eða fjör hafa. Sjaldan liggjandi úlfur
lær um getur né sofandi maður sigur.
