You're lucky some other Alero nut didn't spot that hunk of FG layin on the side of the road and snap it up
I know I would've lol
Shouldn't be too hard to fix.. the good thing about FG is that it's SO forgiving.. if you mess up just grind it down and start again.. and even if you're layup isn't too smoothe, that just means you've got a little extra bodywork to do before it's perfect again.
Good luck.. the key is patience and lots of sanding haha.
