Hey man, I was just busting your chops!!! But seriously before you go getting on a soap box about me reading information I already knew, you may want to think logically here. Of course things will bend or warp under certain degrees of heat. Thats simple science my six year old is learning in school. But there is no possible way his arrows are gonna warp or bend by simply laying horizontal on a wall!! Unless he somehow got the room to 350 degress or higher its not possible. Simple as that
