Eww..was it bad?
not much but it's just on the back but you can't tell from far away XD
lol that's how mine is. since I used acryllic paint, its like real rocky and not smooth at all 
mines came out smooth i lightly use a bit of water and sanded with 2000 grit
2000 grit?
yes for wet sanding it makes the paint smooth
even on acryllac?
yep it's safe
