Question: Which type of stone is better for the statue against acid rain!.!? Red sandstone or peastone!?
Best Answer - Chosen by Asker:

my guess is sand stone!. Peastone is mainly calcium carbonate which won't hold up well to acid (like limestone is calcium carbonate too)!.
also I'd imagine peastone could be really hard to carve, depending on the variety!.Www@QuestionHome@Com
