Is waxing my arms a good idea?

A year or two ago I thought I had really long arm hair (i didn't) and used that pink sand papery thing you can get to remove hair by rubbing it on your skin (from an infomercial, I forget what it's called) anyways, it worked nicely but when the hair grew back it grew back longer and it stuck up in different angles. Before it was flat to my skin.. So now my arms look really hairy, I cant wear t-shirts anymore -_- would waxing them once make the hair grow back properly? How much would it hurt? What would be the best wax for doing this? Would waxing them be weird?
