Found some really fine flexible sand paper/mesh (Mr. Grinding Cloth) that comes in 400, 600, 800, 1000, 2000 and 3000 grades. Got very excited because I really needed something flexible and fine grade to finish the prototype. Ordered it from the hobby store on Friday. Turns out the hobby store ships on Tuesdays and Thursdays and it will be coming from Washington. Estimated date of arrival 3/14/17. Moral of the story: do not order half asleep at 6 am in the morning and read where you are ordering from XD
